| Abstract: | Stray light characteristics of an off-axis three-mirror optical system with a middle image and long-focus was simulated and analyzed,and corresponding suppression method for the stray light was proposed.By a forward and reverse ray tracing method,the main source of stray light was identified and an important surface of the system was found out.According to the analysis results,some corresponding suppression measures were proposed to reduce the stray light of the optical system.The effect of stray light redu... |
