AN/AAS-18 IR Set Modification to Dual Spectrum Capability
Abstract
A system to obtain dual synchronous film records of a target in two different spectrums of the infrared region was required. An AN/AAS-18 Infrared Detecting Set Receiver was modified to contain two different detectors, one of Indium Antimonide, InSb, the other of Mercury-Doped Germanium, GeHg, plus additional circuitry to provide a video output from each detector. Two AN/AAS-18 Recorders and Power Supplies were interfaced together and operated from a common Control Panel to record on film the video information. An amplifier and controls were added to select an infinite value of either or both detector's video to be used with the Air Borne Infrared Raster Display system (ABIRD). As modified, the Dual Spectrum Detection System allows film records of a target to be obtained in the 3 to 5 micron and the 8 to 13 micron regions. The two channels may also be monitored simultaneously on a real-time display of the ABIRD system.
