This is the final report on the Advanced Night Viewer Subsystem ANVS FLIR program. During this program a basic concept was established for a miniature FLIR with a dual field of view that permitted simultaneous operation for 1 flying a Remotely Piloted Vehicle RPV, and 2 tracking targets of interest. The design and fabrication efforts included two airborne sensors, a ground station and two displays to present the separate fields of view. The basic ANVS FLIR concept called for utilizing Texas Instruments FLIR Common Module components, and developing a technique permitting one operator to fly an RPV from one field of view and a different operator to track targets of interest from a separate field of view. This dual capability was achieved by using two separate, but overlapping, optical systems and time sharing their information in the scanner, detector, and electronics. Time sharing was achieved by designing 1 a differential mirror that was synchroneous with the scanner, and 2 electronics to select the fields of view for alternately processing this information into video signals. Provisions for data link techniques for transmitting the video to the ground station which separates the two different fields of view and presents each on separate displays.
