Abstract

We have measured the relative spectral response of MCT infrared detector, and based on distribution of spectral response G((lambda) ), we have calculated the waveband responsivity R_(Delta (lambda) ) and waveband detectivity D*_(Delta (lambda) ) of infrared detector. This paper briefly describes the measure process and results of MCT photoconductive (PC) infrared detector (at temperature 105 K) which is intended to be used in certain waveband for space application, and analyses the measure error.
