Recently the British unveiled details of a new Mercury Cadmium Telluride (HgCdTe) "SPRITE" detector that performs time delay and integration within the material itself. This paper introduces the concept, analyzes and explains the detector's unique features, and presents the results of an experimental investigation, in this country, of both the device and a system utilizing it. Consideration has been given to such system implications as the limitation on the number of detector elements that can be used, power, and scanning speed requirements. Based on the experience and results obtained operating a SPRITE device in a modified discoid system, an optimized TV compatible FLIR system is described and performance predicted.
