Holography is a photographic technique that records the light scattered from an object, and then presents it in a way that appears three-dimensional. Holograms هولوگرام pop up in movies such as Star Wars and Iron Man, but the technology has not quite caught up to movie magic yet.

To make a hologram, هولوگرام you record an object (or person) in a clean environment with a laser beam and apply the information to a recording medium that will clean up and clarify the image.

The laser beam is split in two and redirected with mirrors. One of the beams is directed at the object. A portion of the light reflects off the object and is recorded on the medium.

The second beam (reference beam), is directed toward the recording medium. This means the beams coordinate to make a precise image in the hologram location.

These two laser beams interfere and intersect with each other. The interference pattern is imprinted on the recording medium to recreate the 3D image.

Holograms are as close as your wallet. Most driver s licenses include holograms, هولوگرام as well as ID cards and credit cards. Holograms can even be found throughout our houses. Holograms come as part of CD, DVD, Blu-Ray, and software packaging, as well as nearly everything sold as official merchandise .

But, these security holograms - which discourage forgery - aren t impressive. They simply change shape and color when tilted.

Even marketing departments can thrill customers with holograms هولوگرام through experiential marketing campaigns and 3D hologram interactions.

One product currently in development is called DeepFrame. This holographic tech enables science fiction-like applications, like 3D telepresence. The cost is prohibitive at $50,000, but as the use for experiential marketing and telepresence grows, competition will grow and costs will decrease.

However, new holographic technology is being developed that projects 3D images from another location in real time. The images are also static, but they are refreshed every two seconds, creating a strobe-like effect of movement. The researchers hope to improve the technology over the next few years to bring higher resolution and faster image streaming.

And in March 2013, it was announced that a group of researchers from Hewlett Packard Laboratories has developed glasses-free, multi-perspective, 3D display technology for mobile devices

But, these security holograms - which discourage forgery - aren t impressive. They simply change shape and color when tilted.

However, large-scale holograms, هولوگرام the kind illuminated with lasers or created in a dark room with carefully placed lighting, are phenomenal. They re basically two-dimensional surfaces that show very accurate three-dimensional images of real objects. You don t even have to wear special glasses like when you go to a 3D movie.

3D holograms are coming into our lives. A 3D hologram هولوگرام is an object that isn t actually there, but looks like it is, either floating in mid-air or standing on a nearby surface. This augmented reality ( AR ) is a revolution well on its way.

To create a hologram, هولوگرام you need an object (or person) that you want to record; a laser beam to be shined upon the object and the recording medium; a recording medium with the proper materials needed to help clarify the image; and a clear environment to enable the light beams to intersect.

While it the past it there was a clear distinction technology is evolving to create virtual holograms هولوگرام by steering light into an image. Augmented reality systems like the HoloLens often use a Holographic Optical Elements to make a video projection appear at comfortable viewing distance. The virtual objects in augmented reality are a kind of virtual hologram & not a hologram The Pepper s ghost technique, which uses a partially reflective surface to mix an image with the scene beyond. John Henry Pepper demonstrated the technique in the 1860s with it being used to overlay visual elements (often a figure ghost ) onto a physical set or stage.
