Paper Abstract

Infrared photodetectors having electrical outputs directly proportional to the radiant signal power input can be described in terms of specific and well defined parameters. These parameters and the associated measurement techniques are briefly outlined. Methods are suggested for extrapolating and interpolating from standard report data in order to prepare specific engineering information about expected operational detector performances. Some emphasis is placed on calculating a figure)/ v ss which gives a comparison of quantum detector's response to that of a "black" or "gray" detector for a given spectral content of incident radiant flux. The discussion contains information on current state-of-the-art detectors including those fabricated from the pseudobinary alloy semiconductors mercury-cadmium telluride and the lead-tin chalcogenides.
