  • As the imaging quality of a three line array mapping camera can be reduced by stray light from different optical systems, the effect of the stray light is analyzed according to the result of optical design and a suppression method is put forward to reduce stray light based on the analysis and calculation of the stray light energy, the stray light irradiance on an image plane and the stray light coefficients at the entrance of camera. The stray light models of a three line array mapping camera are built and analyzed by using the software Light-Tools, and the obtained stray light coefficient of each system is less than 5%. Finally, a pratical experiment to test the stray light coefficient is performed by the surface source method and the tested result proves the correctness of the stray light analyzing and the feasibility of the stray light suppression methods.
