Paper Abstract

The development and figure of merit of photoconductive HgCdTe multielement detector used in multi-spectral scanner in thermal IR band are reported in this paper. It focuses on the method of resolving the non-uniformity of spectral response curve for multielement device. The testing and scaling methods on the responsivity R(Delta (lambda) 1) of figure of merit waveband, the detectivity R*(Delta (lambda) 1) of waveband and the responsivity R(lambda ) of monochromatic waveband are also discussed briefly, as well as the situation of aging test and environmental test under space environment condition. The test result shows that the technical index of the multielement device can meet the requirements of space multispectral scanner and its performance is stable and reliable.
