ABSTRACT:
A high resolution infrared scene simulator formed by a novel combination of a photo-cathode, one or more micro-channel plates and a uniquely constructed air-bridge thermal screen. The photo-cathode is used to covert photons into electrons for insertion into the input side of the micro-channel plate. The micro-channel plate is a photo-electric device comprising a parallel array of independent channel, electron multipliers capable of high gain electron amplification. The air-bridge thermal screen comprises numerous thermally isolated thin platelets, bridges or diaphragms whose individual thermal mass and resistance are respectively low and high. Such platelets are thermally isolated and are supported on a structure that is capable of being cooled and electrically conductive.
