Abstract

The phonological network multi-spectral camera has a complicated internal structure. The camera is a composed of eight lenses, and the light path is divided into eight channels. There is a lot of stray light.So deep stray light analysis and suppression design must be performed to reduce the influence of stray light. This paper analyzes the characteristics of phenological network multi-spectral camera system. Two different baffles are designed, and a regional calculation method is proposed to detect the shading performance of the baffle.Then, the stray light analysis was performed on each channel of the phenological network multispectral camera with TracePro. According to the analysis results, PST curves under different conditions are compared, and the appropriate baffle is selected. Finally, shading performance of the baffle was verified through experiments.
