| Abstract: | To perform radation calibration on infrared opto-electric system with a large-aperture,a radiation calibration system based on extended area blackbody and a spectral calibration system based on infrared monochroic collimator were established.The infrared monochroic collimator was composed of a cavity blackbody,a circular variable filter(CVF) and a collimator.It was used to calibrate the infrared opto-electric system spectrally in order to determine its normalized relative spectral response function.A large ... |
