In order to realize the performance test of the spaceborne directional polarization camera (PDC) in the installation stage and environment simulation test, a light source with multi-angle, multi-spectral and polarization features is designed. The final design bases on the principle of the PDC instrument and test requirements is composed of 29 multi-band LED parallel light tubes arranged in a chinese character “mi”-shaped pattern. Through optical modeling, parameters of the parallel light tube diameter, divergence angle and installation field are analyzed. On the basis of radiance calculation analysis, the design of LED driver, diffusion plate, attenuator, polarizer, and depolarizer component was finished, uniform spot illumination and standard polarized light output were realized, the multi-spectral and different dynamic range test of the instrument were satified. The test results show that it meets the multi-field multi-spectral and polarized test requirements, and the stability of source is better than 99.2% within 2 hours, polarization accuracy is better than 1%, reset accuracy is better than 1 pixel. It can meet the requirements of 5% of radiation, 2% of polarization, the performance requirement of geometry 1 pixel, and the monitoring of channel switching function.
