Figure 4.23 shows examples of the characteristic intensity patterns displayed by waves. In figure 4.23a, water waves radiate away from two bobbing floats and form a standing pattern. In figure 4.23b, diffracted X-rays form a similar wave pattern. (...) Both experiments generated patterns like those shown in figure 4.23b, confirming the validity of the de Broglie equation for electron wavelengths. (...) In recent years, scanning tunnelling electron microscopes have produced images of electron waves, an example of which appears in figure 4.23c. Here, two atoms on an otherwise smooth metal surface act like the floats in figure 4.23a, and cause the electrons in the metal to set up a standing wave pattern.

Understanding the atomic density fluctuations in silica glass

In materials science, particularly in the study of glasses, the intermediate range order (IRO) is one of the most intriguing research areas owing to its significant influence over the physical properties of glasses. The IRO refers to the structural arrangement of atoms beyond the short-range order (atomic arrangement within a few atomic distances) but shorter than the long-range order (arrangement patterns over macroscopic distances). Notably, for covalent glasses, the IRO is marked by atomic density fluctuations. Scattering experiments provide a distinct signature of IRO. In these experiments, high-energy beams like X-rays and neutron beams are scattered by the atoms of a sample. The scattered waves then interfere constructively or destructively, resulting in bright or dark spots respectively. The bright spots are called diffraction peaks.

TIL that classical pilot waves were experimentally debunked in 2018. Funny enough, the last time I reblogged a post about them was earlier in 2018.

20ish years ago, a team of physicists observed that droplets of oil bouncing on vibrating water behaved in ways reminiscent of quantum systems. Because the vibrations sort of quantized the water surface, the bounces of the droplets followed quantized steps. Furthermore, the droplets themselves caused displacement of the water, changing the water waves. It all looked sort of like quantized electron orbitals in an atom. And then, of course, if the scientists put in barriers, the droplets could sometimes happen to bounce over them--tunneling. And most astonishing of all, if they placed barriers in a double slit pattern, the wave nature of the water waves guided the droplets into a diffraction-like pattern. That is, the particles behaved like waves because they were simultaneously guided by and inducing waves.

So of course, several groups jumped to try to replicate it. And after about a dozen years they came back with: it didn't work. They didn't see any double-slit diffraction patterns--the droplets interacting with the water waves were not themselves acting like waves. The original experiment had only run 75 times, and had a noisy system; a small sample size plus noise and it was easy to see interference "stripes" that weren't really there. Larger, more careful experiments did not reproduce the results.

There's actually a theoretical reason why classical pilot waves can't reproduce the quantum double-slit experiment. The quantum double-slit experiment is symmetric: the wavefunction passes equally through both slits, and the resulting interference pattern reflects that. That's also true of classical waves passing through a double slit (we did this demo in high school with a tub of water and some bricks). But as soon as you add the oil droplet, the droplet does go through one side or the other, and because its interaction with the waves affects the waves as well as the waves affecting the droplet, that means it breaks the symmetry of the waves themselves. The resulting diffraction pattern is different depending on which side of the double slit the oil droplet goes through.

(Quantum pilot waves don't work quite the same way, so this argument doesn't pertain to them. They're still a viable quantum interpretation.)

Interestingly, the person who came up with the theoretical explanation for why classical pilot waves couldn't reproduce quantum phenomena was Tomas Bohr, Neils Bohr's grandson, who happens to be a fluid dynamics theorist as well as interested in his grandfather's work and so perfectly situated to join this effort. If you're not familiar with the history, the reason pilot wave theory isn't taught in schools and wavefunction collapse is is because Neils Bohr invented the idea of wavefunction collapse and was more powerful within the physics world in the 1920s-30s than de Broglie who invented pilot waves. At this point, nearly a century later, we have no reason to believe one approach is more true than the other--although IMO they're probably different enough to be mutually exclusive. But nevertheless only one of them is taught in schools, unless you're studying quantum fluid dynamics.

Zebra Imaging: The Publically Traded Company In this paper the writer chooses a (public) company that has been a major player involved with the technology that was analyzed as part of the Evolution of a Technology project completed earlier in the course. The company we are going to focus on is "Zebra Imaging," which has been focusing on 3D holographic technology. The paper identifies the overall technology and innovation strategy of Zebra Imaging; analyzes its innovation performance, the actions and choices it has made in creating and capturing value from its innovations. The paper also identifies problems and issues with those actions and choices. The paper provides recommendations for creating and capturing value, identifies key decisions, and recommends how to deliver value (implementation, market approaches, competitive/collaborative issues, etc.). The paper also includes the rationales for the recommendations given in the paper. Lastly, the paper applies the models and analysis tools as discussed in class and identifies key assumptions that underlie the recommendations. Technology Strategy Analysis of Zebra Imaging MIT's Media Laboratory graduates founded Zebra Imaging back in 1996. The company created a mission that focused on the development of the best product and providing the best three dimensional services out there. With help from initial investors the business has made quite the progress since then. Today Zebra Imaging provides some of the most advanced and innovative technology and holographics on the market. The business sells portable, intuitively-understood, and scalable designs that are simple to the eye and that can create reality out of basic data. Customers range from government military departments to high-end private architects, and also anyone who is the need of demonstrating their data in an easy to view 3-D format (Williams, 2014). Identify the overall technology and innovation strategy of your chosen company The future is in 3D and Zebra Imaging is there to sell it. They provide by far the most innovative product out there with holographic capabilities. The basic 3D source can come from a plethora of sources including CAD (computer-aided design), CAM (computer-aided engineering), CAM (medical imaging technologies), laser scans, aerial photography, and LIDAR. This data provides the backbone for holographic software to function (Zebra Imaging Website, 2015). Inference patterns created by lasers are how the hologram is created. The products break down the 3D data into divisions for each hogel (a 3D pixel). The data will usually consist of thousands upon thousands of hogels. Finally the holograph is recorded on a medium such as an LCD screen through the patterns created by the lasers. There are two lasers that create an image on the screen, the first one simply prints the 3D data like an image, but the second one provides a reference point for the first. When the two beams combine, holographics is created (Zebra Imaging Website, 2015). The process described is repeated for every single hogel, so it needs to be done thousands of times (Zebra Imaging Website, 2015). There are no fancy glasses or outside product needed to view the final product the way it is intended to be seen. The light that is used mimics the original reference laser beam. This way each hogels interference pattern plays a role in diffracting the beams light and creating the 3D image to the eye. The user simply sees a refraction of the original 3D model (Zebra Imaging Website, 2015). Analyze its innovation performance When companies defy odds and break innovative barriers they can be awarded with a place in the Technology-Fast 500, and that is exactly what has happened to Zebra Imaging. The company took its place in the group for the second time in a row back in 2008. This is proof that the company is highly innovative and has been keeping a high standard of excellence in its overall performance. The company had an incredible 5-year spurt of growth and success in which it grew by over 1800% (Williams, 2014). The actions and choices the firm has made in creating and capturing value from its innovations. Identify any problems or issues with those actions and choice Unfortunately for retail consumers, they are excluded mostly from the market that the company is focused on. Zebra Imaging have chosen to keep government agencies as well as large scale corporations such as the Zygote Media Group Inc., the Reprographic Services Association, and the Engineering and Construction Companies as their consumers. This has led to the product being very highly priced and excludes a large portion of today's market. That is a large decision made by the company which has ripple effects throughout the rest of the digital imaging industry (O'Toole, 2015). Provide recommendations for creating and capturing value, identify key decisions, and recommend how to deliver value (implementation, market approaches, competitive/collaborative issues, etc.) Although there are a large number of recommendations that can be made for this company, the following is a short list of some of the more important points and suggestions. The rationale for these will be discussed. 1. The company ought to increase its market base by seeking more diverse consumers and clients. 2. The company should maintain all the risks associated with holograms until the product is officially delivered and accepted by the customer. Include the rationales for your recommendations, applying the models and analysis tools discussed in class. 1. Seek to improve customer diversity Partnering with government agencies is not a safe way to do business unfortunately. While the company has had great success, it also required a $5 million federal loan to get them through the crazy 2-week government shutdown in 2013. As of yet the company's primary business target groups have been government agencies as well as a few other large scale corporations. However, the business product would serve multiple industries if Zebra Imaging simply opened its doors to other customers. Revenue could see a drastic increase by opening up for retail consumption. Imagine if the average Joe could capture hologram images with their iPhone, and later print them out. The market is there, the money is there, but the product is not there yet (Jaaskelainen, 2011). 2. Bearing the risks This point should be self-explanatory. According to the company's terms of sale, once an order has been placed, packed up, and sent out via FedEx, it is no longer Zebra Imaging's responsibility. This is wrong and very bad customer service. If a package goes missing or if the product is broken while shipping, it is the customer who gets to deal with it. The company should take responsibility for the product until it has been shipped all the way and accepted by the consumer. It is even worse for international consumers since they are required to pre-pay for the order before it is even shipped. Additionally, all customer data is deleted after 14 days, at least that is the norm. During that time though, the business keeps the right to use your customer data in order to promote or market their business. This is yet another legal issue that the company ought to deal with (Jaaskelainen, 2011). Identify any important assumptions that underlie your recommendations A very big assumption often made is that if Zebra Imaging opens up to retail customers, that they will be able to lower their price due to access to cheaper materials. Whether or not this is true, it is the assumption. Since the company should be able to partner with cheaper material providers, they should be able to lower their product price for retail customers. Identify all the patents that the company has patented The USPTO has approved over 30 patents for Zebra Imaging. Most of these patents relate to the active hologram display but others focus on new inventions in the holography field that are new and different from past products. Unlike the past when there was a strict lens limitation in holograph technologies, we can today create holograms without the use of physical objects. Now we can create this technology from computer generated data. The patents relating to the holographic printers can be looked up in these two patents: 6,661,548B2, and 6,930,811 B2 (Jaaskelainen, 2011). 1. U.S. patent: 6,407,832. Light source following optical system for hologram illumination The system that uses the pulsed-laser was created in order to create both high resolution images and accurate holograms. The imager will be given a certain set of instructions and the pulled-laser system will ensure that the timing of every hogel recording is accurate. Since there are small spots between hogels that this system can't record, it must be shut off while the instrument passes over them (Jaaskelainen, 2011). 2. U.S. patent: 7,505,186. Pulsed-laser systems and methods for producing holographic stereograms Systems focusing on the illumination of holographs with moving light sources. A heliostat device controls the rotation of the deflection mirror and thus directs the light where it needs to go. If there is no light source available then artificial light will be used (Jaaskelainen, 2011). 3. Correcting and Identifying Hogel and Hogel Beam Parameters Application number: 20150053848 Methods and systems that help determine the proper parameter of hogel beams and how they relate to other sets of hogel beams. The system will check and control the hogel beam parameters in order to ensure proper procedure. If the parameters are outside of authorized thresholds, then new values will be assigned (Justia Patents, 2015). 4. U.S. patent: 6,710,900. Holograms exposed and processed on plastic substrates This is a device that has the capability to use holograms to print images with various resolutions from 3D data models. The reference beam moves right along with another object beam that is focused on the surface of the image. The computer calculates the exposure time before the object beam can pass through the image (Jaaskelainen, 2011). 5. U.S. patent: 6,661,548. Method and apparatus for recording one-step, full-color, full-parallax, holographic stereograms The hologram is recorded into material that couples with a surface made of plastic. This is exposed to a small light in order to create holographic elements. The light usually contains a combination of a couple of laser beams to create an interference pattern (Jaaskelainen, 2011). 6. Optics support structures with tapered walls Patent number: 8596838 Stacks of optical components are placed and configured in the walls of various display models so that they can support a transparent structure that covers the whole surface. The walls are all touching where the transparent structure is being tapered (Justia Patents, 2015). 7. Converting 3D data to hogel data Patent number: 8605081 Rendering hogels corresponding to the subsets acquired from 3D data. The 3D data is converted to data that the hogels can be configured by through these systems and methods (Justia Patents, 2015). 8. Pulsed-laser systems and methods for producing holographic stereograms with pre-sensitization of holographic recording materials Patent number: 8665505 Very high quality holograms are recorded through pulsed laser technology in conjunction with pre-sensitization techniques. This is also possible through various other hologram producing hardware and software (Justia Patents, 2015). 9. Multi-core processor architecture for active autostereoscopic emissive displays Patent number: 8736675 Multi-core processors included in a system with an optical display that requires a plethora of hogels. Each individual hogel is created in such a way that it can give off light in many directions. The processor controls the display and the hodels. The processor also needs at least two cores and an on-chip memory system. The master core has to be a part of a an integrated circuit package and be able to control the other cores. All cores are configured to obtain data from the hogels and return corresponding signals (Justia Patents, 2015). There are still a large number of patents held by Zebra Imaging that have not been mentioned. This presentation sought to bring out both some of the older and some of the more modern patents to demonstrate their nature. A more complete list all patents are recorded in the USPTO's database (Justia Patents, 2015). Identify all the major new products (and their time line) the company has launched 1. ZScape® 3D Holographic Prints Viewing these prints is a visual experience that allows you to see information from all angles. The power demonstrated by 3D Holographic Prints is rich, detailed, and more realistic than any other product out there. Through this Holographic printer the audiences can collaborate, comprehend each other, and connect like never before. The uses are incredibly numerous and almost anyone can use the hardware. The machine is important in creating architectural designs as well as creating important 3D medical images. 3D comprehension and understanding is a methodology that has been proven (Zebra Imaging Website, 2015). 2. ZScape®Imagers Producing faster True-3D Holographic Imagery is the purpose of this newly designed product. Incredibly detailed 3D imagery is created almost instantaneously through this hardware and is aimed to please large businesses with heavy demand and high volume needs. Due to the speed and detailed prints from the product, this is the perfect fit for any company that needs a large quantity of work done. Zebra imaging can come and install the product on site or they can maintain the hardware for the consumer at their own facility. The two best perks of this imager are the roll fed film that allows for non-stop printing, even overnight, and the incredibly speedy print times. A1 images can be produced in as little as 90 minutes. The imager is also built with components that are easily replaced and dismantled for easy deployability. Finally, this imager sells for around $500,000 (Zebra Imaging Website, 2015). 3. ZScape® Motion Displays The development of this prototype was helped by the government military defense organization called DARPA (Defense Advanced Research Projects Agency) as part of the UPSD (Urban Photonic Sandtable Display) program. From a meager 6 inches to 6 diagonal feet, this product is scalable and supports real-time sensory data streaming without the need for 3D glasses or other viewing aids. Amazingly enough this allows the product to show large 3D images such as cityscapes or topography that can be viewed by large groups of people at a time (PR Newswire, 2011). Thus instantaneous collaboration and improved planning can be done on site. In 2011 this product was awarded one of the spots in TIME's list of the 50 best inventions. No other product in the world can do what the ZScape ™ Motion Display can do. It is the first of its kind, and the world's very first full-parallax, real-time, and interactive hologram (PR Newswire, 2011). Strategic alliances for new product development and Mergers and Acquisitions for getting access to new technologies Access to new technology has been the motivation for the several acquisitions and mergers that Zebra Imaging has been a part of, and so it has been for their numerous partnerships as well. Another reason has been to increase company growth and revenue so that it was able to advance certain fields of technology. Zygote Media Group has been the world wide industry leader in 3D programming and imagery for medical purposes, and Zebra Imaging recently agreed to a partnership with them to provide service to the market of medical education. This has been a great benefit for Zebra Imaging due to Zygote Media Group having the world's largest and most detailed library in regards to 3D anatomy and biomedical models (O'Toole, 2015). Zebra Imaging now share access to that massive library and will be able to create holographic prints in 3D of the content. This has done wonders for the business in their content strength assimilation (O'Toole, 2015). On the flip side, the zygote customers will also have access to the 3D prints from Zebra Imaging and their holograms of the medical models. These can be accessed directly from a site called 3DScience.com as well as ZygoteBody.com. There will also be additional products created throughout the term of the partnership aimed directly at their medical customers: Hospitals, medical educators, physicians, and pharmaceutical device manufacturers (O'Toole, 2015). Another alliance that was strategically made was with the RSA, the Reprographics Services Association. The partnership was to help Zebra start their rapid expanse into the service of architectural and engineering-based consumers. The RSA boasts a huge network across the nation. They have over 185 locations and are a collaboration of over 80 different businesses. All of the individual companies are well versed and dedicated to the AEC industry. The AEC is the Architecture, Engineering and Construction companies (PR Newswire, 2014). This move by Zebra Imaging was an incredibly wise decision since it gave the company access to huge expansion points all across the American market. The extension of their 3D hologram products into the Architecture, Engineering and Construction companies was very natural since their product was in high demand. Experts have estimated the use of 3D hologram imaging to increase over 50% over the coming years and Zebra Imaging is there to fill the need. Their fast and effective products serve as an easy solution to the industry's needs (PR Newswire, 2014). The digital files stored by the AEC companies can easily be transformed into full 3D holograms in a fraction of the time and at an incredibly cheaper price than the alternatives on the market. They also serve as nice complements to the more traditional 2D blueprints. The rendering of holograms uses the same CAD products that many clients already have in use for their 2D imaging. The images can be generated from a variety of capturing techniques like oblique photography or laser scanning. 3D scanning and visualization is such a powerful tool in the AEC industry because it can give clients a very real idea of what the final product will look like (PR Newswire, 2014). Yet another very strategic partnership and alliance that Zebra Imaging made was with Autodesk. Autodesk started providing a new web service back in 2013 that allowed for 123D-users to print 3D holograms from a model they had created. With the partnership that was created, both companies benefited from their generated growth and revenue, and it also increased their global presence in the world wide 3D hologram industry (PR Newswire, 2013). One development with this partnership is the extension of holographic services to 3D modelers who seek to share their ideas and designs to connect with others. With the ZScape® 3D Zebra Imaging is offering consumers the option to print their creations as a hologram. The price is made affordable due to the business's existing technology and service base. The main theme for this partnership is to inspire and create. The consumers that this partnership targets are those that use creativity to make beautiful and inspiring 3D designs to share with others (PR Newswire, 2013). It is all a big part of steps towards re-imagining digital visualization. Zebra Imaging's part in this is the graphical user interface that they made for Autodesk's web service. This way the users can easily select 3D models online or upload their own. Users can upload or access existing 3D material on Autodesk's site and then through the technology provided by Zebra Imaging, they can print it as a 3D hologram (PR Newswire, 2013).

Diffraction

Diffraction is the bending and spreading of waves, such as light, sound, or water, as they encounter obstacles, slits, or edges. This phenomenon occurs due to the wave-like nature of energy, leading to interference patterns that reveal the wave's behavior. It is fundamental to fields like optics, acoustics, and quantum mechanics. Applications of diffraction range from understanding the structure of crystals through X-ray diffraction to designing optical instruments and studying sound propagation.

What I'm Currently Studying? Holography!

Holography is one of the most captivating branches of optics, blending physics, technology, and artistry to create three-dimensional images that appear almost magical. It’s an area where light’s wave-like nature takes center stage, producing visuals beyond traditional photography's flat confines.

At its core, holography captures and reconstructs the light waves reflected or emitted by an object; unlike regular photos, which only record intensity, holograms encode both the amplitude (brightness) and phase (wavefront shape) of light. This dual information allows holograms to recreate an accurate 3D representation of an object, complete with depth and parallax.

The process begins with a coherent light source—often a laser—split into two beams. One beam called the reference beam, travels directly to the recording medium (like a photographic plate or digital sensor). The other beam, known as the object beam, illuminates the object and then reflects onto the recording medium. When these two beams meet, they interfere, creating a pattern of light and dark fringes. This interference pattern encodes the complete wavefront of the object’s light, forming a hologram.

The real magic happens during reconstruction. When the hologram is illuminated with the same type of reference light, it diffracts to recreate the original wavefronts, making it appear that the object is still present. Walk around a hologram, and you can see different perspectives of the object—a hallmark of accurate 3D imaging.

Holography has found its way into many fields beyond the dazzling holograms in sci-fi movies. In data storage, holography enables massive amounts of information to be encoded compactly—medical imaging benefits from holography’s ability to produce highly detailed 3D views of tissues and organs. Even in engineering, holographic interferometry helps detect minute deformations in structures, ensuring safety and precision.

What makes holography so fascinating is how it bridges physics and perception. It vividly demonstrates light’s wave nature, where interference and diffraction transform simple beams into immersive visuals. As I study this field, I’m struck by its blend of rigorous science and boundless creativity—showing us not just how we see the world but how we can reimagine it.

Holography isn’t just about recording; it’s about bringing light to life. And as technology evolves, the possibilities for this incredible phenomenon continue to expand, promising innovations that feel like stepping into the future.

[ad_1] Have you learnt of a sticker that appears like a rainbow gentle bulb in its colors and will get even brighter and sparklier when moved? Or is it one color once you lean it barely and one other once you lean it a bit extra?  Consequently, these stickers are known as holographic stickers, and they're such a rarity that they're more and more gaining reputation. Vograce holographic stickers are notably miraculous due to this type of reflection that may make rainbow-like and shine. However why are these stickers so distinctive? One should marvel how they obtain such lovely colors and results. That’s what we'll talk about on this article, or extra particularly, how gentle is liable for the true colour-changing capabilities of holographic stickers.  By the top of this text, I’ll clarify how this mix of sunshine and color creates the mesmerising impact seen within the Vograce holographic stickers! How a Holographic Sticker is Outlined Let’s begin with what a holographic sticker is earlier than we speak concerning the science behind it. A holographic sticker is a selected sticker that, when scratched or uncovered to gentle, has a rainbow impact, dazzling.  When you flip the floor like a lightweight or create some form of rainbow pattern-like impact, there may be an impact. This happens as a result of gentle behaves in a selected method when it interfaces with the sticker’s floor. One may very well be forgiven for initially considering that any given holographic sticker was a piece of magic, however in truth, it's a science trick referred to as gentle diffraction. Mild diffraction is how gentle is scattered because it passes by specific surfaces.  The alternative floor of the holographic stickers under is made from some materials that may change the route of the sunshine to type the shiny and vibrant layers we observe. Subsequent, let’s evaluate how gentle and colors begin the marvel of holographic stickers! Understanding Mild and Shade Earlier than we perceive how holographic stickers work, we should perceive one thing about gentle. Mild is taken into account a wave of a selected sort of vitality. These waves are extraordinary as a result of they will switch in area and likewise switch color.  We see colors as a result of completely different wavelengths of sunshine. Each color has its distinctive vary of wavelengths, with the purple ray having the most important wavelength and the violet ray having the shortest wavelength. Relying on the interactions of the sunshine with an object, a number of the gentle is absorbed by the item, a number of the gentle displays off the item, and others penetrate by the item. It's true that what we understand as color is set relying on the sunshine being mirrored off the item.  As an example, when an individual sees a purple apple, it seems purple as a result of it would mirror purple gentle however won't take up some other one. In the identical approach, the holographic affect on stickers happens due to the reflection of sunshine on the sticker’s physique. Mentioned the Science of Diffraction and Reflection Let’s discover the 2 basic scientific ideas that make holographic stickers unforgettable: diffraction and reflection. Interference happens when waves of sunshine journey by a fabric containing small scales or ridges. These grooves are so small that they alter the route of the sunshine, bending or spreading it. That is what makes the colors on a holographic sticker fade and alter when the sticker is moved.  There are patterns on the skin of the sticker, so when gentle shines on the shapes, the sunshine breaks up right into a combina­tion of colors, simply as a prism breaks white gentle in order that it might rain. After message creation, the hologram is the third part, and reflection is the final a part of the holographic impact. Letting gentle fall on the floor of a holographic sticker, it's partially mirrored. This makes the sticker extra engaging because the place the place you stick the sticker has the colors of the sticker, which makes it extra noticeable. 

That is achieved by utilizing a holographic sticker since every a part of it's meant to mirror gentle in a fashion that types a number of layers of color within the sticker, thus giving it a distinct look when a distinct angle of view is utilized. Diffraction and reflection are mixed to trigger the change in hue over the lifetime of the Vograce holographic stickers. How Microscopic Holographic Movie produces the color impact Holographic stickers are produced utilizing a movie on which micro-relief patterns are utilized. This movie provides the sticker that shiny, rainbow-like look you see within the image. The holographic movie is thus constructed of skinny layers of fabric which have been handled to create patterns within the miniature and actual vary.  These patterns are tiny and should not noticeable even with a daily handheld lens, but they play an important position in manipulating the sunshine results we observe. Every time gentle is incident on the holographic movie, the microstructure on the floor distorts the sunshine waves and disperses them. This births the rainbow impact as a result of the vary of colours in gentle is effectively unfold out and deflected at completely different angles. The given frequency implies that the dimensions and form of patterns on the holographic movie outline the colors we see. That's the reason films could produce a number of outcomes and go away completely different impressions in audiences’ minds. Relying on the precise method employed, some movies could make a faint gleaming or sheen, whereas others could yield surprising colors like these on the rainbow.  Vograce utilises holographic movies of their stickers to make sure they appear unbelievable from all angles and have a top quality really feel. That is why Vograce’s holographic stickers are so distinctive; the standard of the movie is so good that the stickers shine, have the suitable colors, and are sturdy. The Integration Of UV Printing in Holographic Stickers Along with the engaging holographic stickers, Vograce takes an additional step by utilising a printing approach referred to as UV printing. UV printing is a way by which the ink used dries by irradiation with ultraviolet (UV) gentle on the identical time the print is made. The UV gentle makes the ink adhere effectively to the holographic movie, leading to a energetic and clear design. UV printing doesn't fade the sticker’s colors, even when uncovered to sunshine. When you ever end up with a sticker that loses its color once you put it out within the solar, then you'll love how UV printing retains Vograce stickers daring and vibrant for a very long time.  UV printing makes the holographic sticker’s design simply seen in opposition to the shiny, colour-change background. Utilizing each holographic movie and UV printing applied sciences, Vograce’s stickers look good and last more. For the Holistics of Vograce, How is the Holographic Sticker Made Their predominant product is holographic stickers, which they provide as customized services and products to their shoppers.

Theoretical astrophysicist proposes solution to enigma of Crab Nebula's 'zebra' pattern

A theoretical astrophysicist from the University of Kansas may have solved a nearly two-decade-old mystery over the origins of an unusual "zebra" pattern seen in high-frequency radio pulses from the Crab Nebula.

His findings have just been published in Physical Review Letters.

The Crab Nebula features a neutron star at its center that has formed into a 12-mile-wide pulsar pinwheeling electromagnetic radiation across the cosmos.

"The emission, which resembles a lighthouse beam, repeatedly sweeps past Earth as the star rotates," said lead author Mikhail Medvedev, professor of physics & astronomy at KU.

"We observe this as a pulsed emission, usually with one or two pulses per rotation. The specific pulsar I'm discussing is known as the Crab Pulsar, located in the center of the Crab Nebula 6,000 light years away from us."

The Crab Nebula is the remnant of a supernova that appeared in 1054.

"Historical records, including Chinese accounts, describe an unusually bright star appearing in the sky," said the KU researcher.

But unlike any other known pulsar, Medvedev said the Crab Pulsar features a zebra pattern—unusual band spacing in the electromagnetic spectrum proportional to band frequencies, and other weird features like high polarization and stability.

"It's very bright, across practically all wave bands," he said. "This is the only object we know of that produces the zebra pattern, and it only appears in a single emission component from the Crab Pulsar.

"The main pulse is a broadband pulse, typical of most pulsars, with other broadband components common to neutron stars. However, the high-frequency interpulse is unique, ranging between 5 and 30 gigahertz—frequencies similar to those in a microwave oven."

Since this pattern was discovered in a 2007 paper, the KU researcher said the pattern had proved "baffling" for investigators.

"Researchers proposed various emission mechanisms, but none have convincingly explained the observed patterns," he said.

Using data from the Crab Pulsar, Medvedev established a method using wave optics to gauge the density of the pulsar's plasma—the "gas" of charged particles (electrons and positrons)—using a fringe pattern found in the electromagnetic pulses.

"If you have a screen and an electromagnetic wave passes by, the wave doesn't propagate straight through," Medvedev said.

"In geometrical optics, shadows cast by obstacles would extend indefinitely—if you're in the shadow, there's no light; outside of it, you see light. But wave optics introduces a different behavior—waves bend around obstacles and interfere with each other, creating a sequence of bright and dim fringes due to constructive and destructive interference."

This well-known fringe pattern phenomenon is caused by consistent constructive interference but has different characteristics when radio waves propagate around a neutron star.

"A typical diffraction pattern would produce evenly spaced fringes if we just had a neutron star as a shield," the KU researcher said. "But here, the neutron star's magnetic field generates charged particles constituting a dense plasma, which varies with distance from the star.

"As a radio wave propagates through the plasma, it passes through dilute areas but is reflected by dense plasma. This reflection varies by frequency: Low frequencies reflect at large radii, casting a bigger shadow, while high frequencies create smaller shadows, resulting in different fringe spacing."

In this way, Medvedev determined the Crab Pulsar's plasma matter causes diffraction in the electromagnetic pulses responsible for the neutron star's singular zebra pattern.

"This model is the first one capable of measuring those parameters," Medvedev said. "By analyzing the fringes, we can deduce the density and distribution of plasma in the magnetosphere. It's incredible because these observations allow us to convert fringe measurements into a density distribution of the plasma, essentially creating an image or performing tomography of the neutron star's magnetosphere."

Next, Medvedev said his theory can be tested with collection of more data from the Crab Pulsar and fine-tuned by factoring in its powerful and strange gravitational and polarization effects. The new understanding of how a plasma matter alters a pulsar's signal will change how astrophysicists understand other pulsars.

"The Crab Pulsar is somewhat unique—it's relatively young by astronomical standards, only about a thousand years old, and highly energetic," he said. "But it's not alone; we know of hundreds of pulsars, with over a dozen that are also young.

"Known binary pulsars, which were used to test Einstein's general relativity theory, can also be explored with the proposed method. This research can indeed broaden our understanding and observation techniques for pulsars, particularly young, energetic ones."

Medvedev modeled wave diffraction off a circular reflecting region with radially varying index of refraction outside of it to better understand the Crab Nebula's zebra pattern. Credit: Mikhail Medvedev

[mars2lh-f]

The science behind holograms

Holography is a fascinating scientific technique that enables the creation of three-dimensional images through the principles of interference and diffraction. The foundation of holography lies in the coherence of light, specifically laser light, which exhibits a consistent phase relationship among its waves. This coherence is crucial for generating the interference patterns necessary for holographic imaging.

To create a hologram, a laser beam is split into two components: the object beam and the reference beam. The object beam is directed onto the subject, and the light scattered off the object combines with the reference beam. The resulting interference pattern, containing both amplitude and phase information, is recorded on a photosensitive medium such as a holographic plate or film.

Unlike traditional photographs that only capture intensity information, holography preserves the wavefront information of light, allowing for the recreation of a 3D image. When the hologram is later illuminated with a coherent light source, such as the same laser used during recording, the interference pattern is reconstructed. This reconstruction results in the perception of a lifelike 3D image, complete with parallax, enabling viewers to observe the holographic object from different angles.

Holography has found diverse applications, ranging from art and security to data storage and medical imaging. The ability to create realistic 3D images with parallax has made holography an invaluable tool in various fields, continually advancing as technology evolves.
