Military night-vision upgrade

SA Photonics Have released their High Resolution Night Vision System (HRNVS) to replace the decades old technology being used today. Former night vision systems gave airforce pilots a total field of view of 40 degrees, horizontally. SA Photonics HRNVS over doubles that to 82.5 degrees. 4 individual Intevac Model 11 EBAPS digital night vision cameras make up the system, capturing 1600 x 1200 pixels per. High speed digital image processing comes via Rockwell Collins Display Systems "Microcore" platform. The HRNVS also topples various other common issues with night-vision. The Halo Effect is completely reduced using proprietary technology. Each eyepiece of the HRNVS is a seamless panoramic display, that can be individually stowed. Digital image enhancement of the images is also an option. The user views through two eMagin SXGA (1280 x 1024) displays, boasting almost 4 megapixels per eye. The HRNVS shows a panoramic view of 82.5 degrees using binocular overlap. Each eye piece shares about 27.5 degrees of view.
 
SA Photonics concludes their introduction with future predictions. Wait a little while longer and get the 100 degree field of view with color displays.

    DAB,

    Since you worked so close to pilots, how do you think they would feel if their complete vision range was covered by some future night vision system? I am under the impression that the pilots looked out of their window still due to the fact that the actual FOV in goggles was so small.

  • One thing I learned during my days of of advanced avionics is that you do not want to block both eyes of a pilot.  Even though your normal vision cannot see in the dark, there are all kinds of things that can blind the IR goggles.  Plus, we found that most pilots are a lot more comfortable with night vision if they can still see out of the window.  If you want to fly via sensors, you might as well go fly the UAV's.

    Most of the search and rescue folks I worked with always had someone looking out of the windows in addition to all of the fancy IR sensors.  That way you get all of the information in real time and sometimes your eyes will see things outside of the normal frame of vision that is essential to the decision making process.

    Thanks,
