Abstract

Variations of peak detectivity D*(λ_p) and peak responsivity R_V(λ_p) values with background flux density have been examined on Photoconductive Mercury-Cadmium Telluride / Hg_1-xCd_xTe (PC MCT) infrared radiation detectors. Measurements were performed at operating temperature T_op ≈ 78 K. Performance was measured on multi-element PC MCT infrared radiation detectors (N = 3x32 and 128 elements) with responsivity peak wavelength λ_p from 10,5 to 12,0 μm at the integral background flux density varied from (8-10)E+17 to (6-8)E+15 photon•cm^-2•sec^-1. Tested PC MCT infrared radiation detectors demonstrate background limited performance (BLIP).
