Abstract
An infrared detector in the form of a focal plane array containing infrared detectors of two sensitivity types is disclosed. The detectors may be based on alloys of HgCdTe with cutoff wavelengths of 5 microns and 10 microns. The two types of detectors are in close proximity and thereby avoid the time delay problem. The two spectral sensitivities make possible the determinaton of spectral signatures and target identification. Further, the two types of detectors are arrayed to permit use of a single set of read lines together with electronic addressing for selecting the detector type, thereby simplifying the output structure and processor design.
