Infrared Scene Displays And Their Use In Detector And Processor Assessment

Broad bandwidth infrared display systems have been developed for use in evaluating infrared imagers and processors. The displays use electrically heated diode resistor arrays as the emitting devices which are line at a time addressed. The displays have a black body emission spectrum and accept data electronically. Maximum display temperature exceeding 25K, temperature resolution of 0.1K and a time constant of 10 msec have been demonstrated in a 100 line system.
