摘要
基于光学设计软件ZEMAX, 通过Monte Carlo光线追迹法, 对比研究了采用三种设计方式的二次反射聚焦系统在不同类型角度偏差下的聚焦性能参数的变化。结果表明:任何微小的角度偏差都会导致聚焦性能急剧下降和聚焦位置大幅偏离。聚焦系统存在角度偏差时, 不同设计方式的聚焦系统会形成不同形状的点火区域, 这将导致激光推力器产生完全不同的飞行的轨迹和姿态。
Abstract
Based on optical design software ZEMAX and the Monte Carlo ray tracing method, a comparative study of three design methods of double-reflection focusing system under different angle aberrations are undertaken. And focusing performance parameters on the focusing plane are analyzed. The results show that any slight angle aberrations can lead to intense deterioration of the focusing performance and large deviation of the focusing location. When there is the angle aberration of the focusing system, different shapes of ignition areas appear for different design methods, which give rise to different flight trajectories and attitudes for the laser thrusters.
