Mandatory objectives. Following objectives are required to be achieved. 1. To make helmet mounted digital night vision devices. The devices will use digital CMOS sensors or equivalent digital sensor to amplify light and show the image to the pilot on integrated display. 2. Adapt these devices to existing helmets for flying in fighters, helicopters and transport aircraft and tactical helmets for IAF special forces. 3. Device should be binocular and focussed at infinity. 4. Should be robust to take on the rigours of flying environment. 5. lt should have following technical capabilities: 5.1 Sensor Resolution: 1280 x 1024 or better. 5.2 Frame Rate ≥ 60fps 5.3 FoV: ≥ 40degrees 5.4 Spectrum of operation: 400-1100 nm or wider. 5.5 AMOLED/ Micro LED Display: 1920 x 1080. 5.6 Diopter Adjustment: -4 to +4 5.7 Eye relief: 25 mm or more. 5.8 Built in compass, GPS, and 3D orientation sensor. 5.9 On board storage: 14 hours of video on removable card. 5.10 On board battery: Preferably rechargeable or COTS replaceable. 5.11 Quick disconnect mechanism for any component projecting outwards (front or sides) of the helmet. 5.12 Size should be smaller or equal to existing NVG F4949. 5.13 MIL STD 810 drop test. 5.14 Flexible mounting options for various helmets. Baseline helmet will be MSA Gallet LA100, available with lAF. Desirable objectives 1. Overlay digital information on the night vision video. 2. Automatic detection of certain objects/ shapes in the video i.e high terrain, other aircraft, rotating objects, obstructions, humans, vehicles, pre fed or pre-determined waypoints, etc.
