| Abstract: | The Monte-Carlo method is introduced to a na lyze suppression of stray light. This paper puts emphasis on its principle and m odelling, including the basic idea, mathematic model and the probability model o f the surface radiation. Then stray light propagation to a typical star sensor f or spacecrafts has been simulated. A model of stray light propagation was built for analyzing the stray light under complex environment. Quantitative contributi on of the environment of the stray light to the star sensor is calculated, the s tray light propagation inside the light-shield with large attenuation ratio and the optical system has been tracked, finally the suppressing capability of the l ight-shield obtained. < |
