Variations of peak detectivity D*(lp ) and peak responsivity RY(lp ) values with background flux density have been examined on Photoconductive Mercury-Cadmium Telluride/Hg1-xCdxTe (PC MCT) infrared radiation detectors. Measurements were performed at operating temperature Top @ 78 K. Performance was examined on multi-element PC MCT infrared radiation detectors (N = 3x32 and 128 elements) with responsivity peak wavelength lp from 10,5 to 12,5 mm at the background flux density from (8–10)E+17 to (6–8)E+15 photon*cm2*sec-1. Tested PC MCT detectors demonstrate background limited performance (BLIP).
