Abstract

The advanced image intensification system (AI^2/ is an advanced technology demonstrator that incorporates several new improvements into a direct view night vision device. An electroluminescent display (ELD) panel was integrated into the AI² monocular. This development placed a transparent ELD panel in contact with the output image plane of the intensifier such that the intensified image and the video image are viewed simultaneously. Additionally, the device field of view was increased to 60 degrees from the 40 degrees that is typical for presently fielded night vision devices. The incorporation of a display and an increased field of view into a night vision monocular resulted in a new optomechanical architecture that was driven by the cumulative requirements of this program. Several advancements were also incorporated into the intensifier assembly. An automatic photocathode gating scheme was developed and proven in this effort. A user adjustable variable intensifier gain was also incorporated into this system. Test data verifying the basic feasibility of the AI² design was taken and user evaluations (infantry and aviation) have been conducted.
