CTF Photonics - CTF-3 Laser Aiming Module

So far it seems very well-constructed. The CNC billet 6065 aluminum body feels solid, the rail clamp is well thought-out, the and the battery caps don't impede button activation as much as I thought they would.

However, getting the bad out of the way first, the adjustment turrets, contrary to my original assumption, do not feature 'clicky' MOA increments - they seem like they've got an internal o-ring somewhere to tension the screws for zeroing adjustment and the marks on the vertical turret are just there as witness marks more than actual adjustments.

Additionally the screws are small and seem easy to strip for how much pressure's needed to turn them. But for they do seem like they'll hold zero no issue once adjusted, for what it's worth.

The unit is incredibly low-profile as you would expect - an IR-only laser diode sits center over bore with what amounts to two independent 300-style scout flashlight bodies sitting saddleback on either side of the top rail. One holds a white light and the other would hold some form of IR illuminator head (B.E. Meyers KIJI, Z-Bolt Blazer, 3EIR Vulcan).

It seems like a good solution for secondary or tertiary builds that you wanna tack NV capabilities onto. Incidentally, due to being so low-profile, it's the perfect MFAL for an AK or other rifles that you can't put excessively tall optic risers on due to the stock being lower than the top of the receiver.

I've ordered a Z-Bolt Blazer Head and will be donating this laser to @bureau-of-mines' AK in trade for a Holosun IRIS-3 or AMMJ Penumbra (depending on whether the former restocks before I make up the additional cash to afford the latter).

For the sake of comparison, here's the CTF-3 without any heads in between a Steiner DBAL D2 and an EG NGAL.

The CTF-3 seems like a large unit, but it's very flat and carries most of its weight in the integral flashlight bodies, which it spreads out nicely. Plus the fact it eliminates a separate white light setup also cuts down greatly on weight.

While I don't recommend this unit for AR15's (given the abundance of better options now), I'd say it still has a niche to fill. Basically, it's a DIR-V that traded the lighter weight and the crane port for superior build quality and sheer modularity. And also not costing $2000 fucking dollars.

New high-power thermoelectric device may provide cooling in next-gen electronics

Next-generation electronics will feature smaller and more powerful components that require new solutions for cooling. A new thermoelectric cooler developed by Penn State scientists greatly improves the cooling power and efficiency compared to current commercial thermoelectric units and may help control heat in future high-power electronics, the researchers said. "Our new material can provide thermoelectric devices with very high cooling power density," said Bed Poudel, research professor in the Department of Materials Science and Engineering at Penn State. "We were able to demonstrate that this new device can not only be competitive in terms of technoeconomic measures but outperform the current leading thermoelectric cooling modules. The new generation of electronics will benefit from this development." Thermoelectric coolers transfer heat from one side of the device to the other when electricity is applied, creating a module with cold and hot sides. Placing the cold side on electronic components that generate heat, like laser diodes or microprocessors, can pump the excess heat away and help control the temperature. But as those components become more powerful, thermoelectric coolers will also need to pump more heat, the scientists said.

TINEE

Oh. my. Gosh. These things are SO SMALL. I got my new laser modules from overseas, and I've been tuning them up for use once I build a 3 tiered enclosure to hold 2 3d printers and 2 laser engravers(This thing is gonna reach the ceiling, have built in power, light, fire detection, cameras... and cost me like $800 once it's all said and done probably XD). These tiny little masterpieces were engraved using the Neje B30365 optical module. It has the smallest laser spot size I've ever seen on a diode laser. a mere .02mm square!!!! This thing is so small that my laser software issued me a literal "Sanity check" window, telling me that very few lasers in the WORLD can engrave at this level of detail. I didn't expect to have as much fun as I am with this module(The least powerful of the 3 new optical modules I got) but it has been the most fun so far with my new machines!! What you see on screen took a total of around 2 hours. Detail comes at a cost, and that cost is maaajor time. I could whip these out in half the time at twice the size on my other lasers, but the detail would not compare. apologies for the ramble, these new toys are sick and I must express!!!  I did not have any of my own grayscle ready images on hand, so these were the ones that were chosen. I had Dall-E create the black hole scene. The Lackadaisy pic belongs to the talented artists over on the Lackadaisy channel of course! I couldn't resist putting that little guy on my hat.. Just look at that face!(If you guys want it taken down no problem, just let me know!)

Quantum LiDAR Improves Sensor Remote And Noise Rejection

Quantum LiDAR

Light identification and Ranging (LiDAR), a vital remote sensing technology, is poised for a major transformation thanks to cutting-edge quantum-enhanced and quantum-inspired research. Ground surveys, sea level monitoring, and autonomous vehicle navigation require LiDAR. It creates a 3D image by shining laser light on an object and measuring the reflected light.

Traditional LiDAR systems have many limitations, especially in tough settings. In poor light, weak signals, or considerable background noise from purposeful jamming or the environment, LiDAR has classic issues. Inability to distinguish signal and noise photons lowers SNR, making target identification impossible. Classic rangefinding methods sometimes require temporal alteration of the light source, which reduces covertness and makes the system vulnerable to jamming or spoofing by uncooperative targets.

Overcoming Noise and Jamming with Quantum-Enhanced LiDAR

Recent findings show how quantum principles can fix these weaknesses, particularly by exploiting photon pairs’ large temporal correlations. A quantum-enhanced LiDAR system was created by Strathclyde University academics M. P. Mrozowski, R. J. Murchie, J. Jeffers, and J. D. Pritchard. Even with high, time-varying classical noise, our system can identify and rangefind targets.

Their 2024 Optics Express study shows that they can detect targets with reflectivities as low as -52 dB and operate with a signal-to-background separation of more than five orders of magnitude.

A 405 nm pump laser on a ppKTP crystal generates heralded photon pairs by spontaneous parametric down-conversion (SPDC) in the Strathclyde system. Utilising these photon pairs’ high temporal correlations is a major advance. One photon (the “idler”) is detected locally, and its counterpart (the “signal”) explores the target.

Concurrent detection, in which a signal photon is reported only when its idler counterpart is detected, can reduce background counts and boost SNR. This technology makes it harder to spoof or intercept by allowing distance information to be extracted from the temporal delay at which a correlation is recognised without laser temporal modulation.

This quantum-enhanced approach improves performance. With 17 times faster target identification and a comparable error rate, it improved SNR by 30 dB over traditional lighting. Most notably, the system survived sluggish, high-frequency classical jamming. The system naturally resisted fast noise, but a new dynamic background tracking strategy that used a pre-calculated look-up table based on raw signal data protected it from moderate background oscillations.

Strathclyde exhibited moving target discrimination for rangefinding with a spatial resolution of 11 cm, but timing jitter from room-temperature single-photon avalanche diodes (SPADs) was the key restriction. Future integration with superconducting nanowire detectors may reduce timing uncertainty, despite SPAD resolution limitations. By making CW sources look as dim thermal sources, they limit spoofing and increase illumination covertness.

Millimetre-Level Precision Driven by Quantums

The University of Bristol Quantum Engineering Technology Labs have also developed “entanglement-inspired frequency-agile rangefinding” as a promising option. Weijie Nie, Peide Zhang, Alex McMillan, Alex S. Clark, and John G. Rarity created coupled photons using a classical laser to replicate quantum entanglement’s noise robustness. This technology overcomes genuine  quantum computing’s brightness limits to attain a brightness more than six orders of magnitude higher than typical quantum sources.

Despite challenging daylight conditions, the Bristol system achieved 0.1 mm precision over 150 meters with 48 µW optical power and 100 millisecond integration time. This millimeter-level accuracy held through changing weather and solar backdrops. The new system architecture includes a frequency-agile pseudo-random generator to finely manipulate photon characteristics via fibre chromatic dispersion and pulse carving. Operating at modest transmission power improves its long-term usefulness and real-world deployment.

Statistical Advantage: Log-Likelihood Framework

Advanced statistical analysis benefits quantum-inspired and quantum-enhanced approaches. Strathclyde uses log-likelihood value (LLV) rangefinding and target recognition. This method determines if statistics support hypothesis 1 or 0. Higher target presence is observed at Λ>0, the LLV’s self-calibrating threshold (Λ=0). This method works well when the signal-to-noise ratio is low and standard methods fail.

The LLV framework may analyse data from several detector channels, including noncoincidence click information that present procedures miss, to improve state discrimination. This dependable statistical technique shows that quantum-enhanced systems outperform classical systems in high background-noise and low signal strength environments. Under the same conditions, the quantum-enhanced system had a peak distinguishability of 0.995, compared to 0.63 for the classical system.

Future View

These findings show that quantum correlations can enable lower light levels, faster detection, and more complex LiDAR applications that demand security and performance. Hybrid quantum-classical systems can increase performance and air turbulence resilience with these technologies.

LiDAR technology has advanced significantly and could improve situational awareness and enable more reliable autonomous systems in difficult real-world scenarios due to the inherent covertness of CW quantum-enhanced sources and the ability to confidently detect and rangefind in previously unmanageable noise conditions
