Abstract: In order to meet the requirement of calibration of ground calibration equipment for space optical remote sensing instrument, based on the principle of radiance transmission of standard detector, a multi-band spectral radiometer based on diaphragm structure is developed. The working principle and development process of the multi-band spectral radiometer are introduced. The instrument has 10 measurement channels distributed between 400 nm-1000 nm, which is divided by narrow band interference filter. With the aperture of the field of view and aperture of the aperture to limit the incidence area and the stereoscopic angle, and the silicon photodiode detector is used as the detection unit. The instrument has the stability of the self calibrating light source monitoring system. The CCD sighting device is used to realize the visualization of the observation targets, and the measuring process is simple. The uncertainty of measurement of the spectral radiance of the instrument was been evaluated, and its measurement uncertainty is better than 1.3%.
