Abstract

The problem dealt with concerns the degradation of an ir detector's performance when operated at background light levels greater than those encountered under normal laboratory conditions. It is shown that the loss in detectivity experienced by photon noise limited intrinsic cells must be attributed to enhanced noise generation resulting from the incremental effective irradiance falling on the detector. The procedure outlined here provides guidelines for assessing photosaturation effects in ir systems designed for applications involving high velocity motion through the atmosphere.
