HISAR Laser Proximity Sensor detectors compared to German's detector that they won't sell

BTW laser proximity sensor for HISAR is co-developed with Thales UK - Belfast

But it was said that hisar uses rf proximity sensor

High efficiency nanohole based immersion metalens for light concentration
6 August 2021 ASELSAN

Abstract

Design and performance analysis of a high efficiency, nanohole based, polarization-insensitive, all-dielectric, immersion metalens is presented, which is to be monolithically integrated into a backside illuminated HgCdTe based photodetector with CdZnTe (4%) as the substrate material for MWIR (3-5 μm) applications. Although HgCdTe based IR imaging dominate the high-performance end of the market, enhancing the signal-to-noise ratio (SNR) performance is still one of the challenges. This is typically dealt with either by improving the quantum efficiency (QE) with the employment of AR surfaces and photon trapping schemes or by decreasing the noise level with a reduction in detector volume. Decreasing either the thickness or the area of the detector, which comes with a performance degradation in QE in return, does the volume reduction. Nevertheless, the reduced QE can be recovered through light concentration with the employment of microlenses in the case of reduced area, which is typically realized with curved lenses presenting curve formation and packaging related issues. These issues can be overcome with the utilization of lithography-compatible metalenses carved into the substrate material. Thus, in this study, a nanohole based array of 40×40 is optimized to be monolithically integrated into CdZnTe (4%) substrate with a placement period of 1.0μm, a depth of around 4.9μm in order to construct a metalens structure with a numerical aperture of 0.63, and operation wavelength of 4.0μm. The nanohole width changes within a range of 0.35μm to 0.83μm in order to provide 2π phase coverage. Single layer of SiO2 based antireflective surface is introduced to the design in order to enhance the focusing efficiency, which is determined to be around 91%.

Bro, I think we can see such a sophisticated 3-mode system in another missile that will engage ballistic missiles. As far as I know THAAD uses 2-color MWIR/LWIR 640x512 FPA. This system will even be more advanced than THAAD's IIR seeker.

Its not necessary for land-land missiles ..those sophisticated seekers will be suitable for A2A or land-air missiles

And when we are getting a dual mode seeker with a hollow aesa radar in the same configuration as in the image?

Optical design of triple-mode seeker (Interpretation of the OMTAS anti-tank project with imported detectors. There is no information on national detector work.)

In missile applications, new counter measure methods are getting more complex. To discriminate and detect
counter measure and to understand target signature from scene is getting harder. Because of all that concerns,
using triple-mode seeker for a system solution is a good solution for system total performance. By this way, tridifferent wavelength could be used for same system and same scene. In this study, triple mode system’s optical
designs have been made for mid-wave infra-red imaging, long-wave infra-red imaging and short-wave infrared
imaging. Optical designs performances have been illustrated in simulation results. Finally, conceptual design of
triple mode seeker will be summarized.

I shared the link to the article.

Yesterday I was thinking where FLIR fits on T-70. Now I know

https://twitter.com/i/web/status/1435569354909831171

Early T-70 will not have R-400D. It needs modification first.

It'll be super expensive if all T-70s were to be fitted with R-400D. Likely majority of T-70s will be without, with only specialised helicopters being fitted with E/O balls.

Guys, I have a question. In IDEF 21, it is written that the deliveries of the MİLKED 3a3 system will begin in 2022. So who has been performing the task of electronic support in the v/uhf band until now?

Hmm can we turn some into CSAR with indigenous sensors, countermeasures, FLIR and other systems? How much fuss would the US make.

The contract includes those. There is nothing to fuss about. That's why it is called T-70.

'CENK fully matches the requirements of most challenging long-range anti-air warfare operations of corvettes, or frigates with its dual-axis AESA technology. On the other hand, MAR-D 3D Search and Surveillance Radar with its AESA architecture is the best-fit for smaller size crafts with its low SWaP requirements.'
