摘要
快速反射镜是复合轴精密跟瞄系统的核心之一。为研究解耦快速反射镜旋转引起的光束偏转, 将快速反射镜的转动分解为纵轴和横轴的运动, 并建立空间直角坐标系。分别进行快速反射镜纵轴、横轴转动, 通过理论分析, 确立光束偏转与快速反射镜转动在空间直角坐标系内基本关系。针对典型情况, 分析出上述关系的简化模型, 便于工程简化运算, 并通过仿真进行了验证。
Abstract
The fast steering mirror (FSM) is one of the core parts in the composite axis precision tracking system. In order to research the beam deflection caused by decoupling FSM rotation, the FSM rotation is decomposed into longitudinal and transverse movement, and the space rectangular coordinate system is established. Rotating the FSM longitudinally and transversely, the cardinal relationship of the angular variation of the reflection rays in the FSM coordinate system is established theoretically. Based on the typical models, the simplified model in the azimuth and pitch direction is constructed. In this way, the engineering calculation could be simplified, and the results are verified through simulation experiments.
