摘要
设计了一种能够应用于空间光通信的大角度高精度光束偏转系统。系统采用液晶空间光调制器(LCSLM)实现小角度光束偏转,采用多Wollaston棱镜级联实现角度放大。介绍了LCSLM和Wollaston棱镜的光束偏转原理,并对大角度高精度光束偏转系统进行了仿真分析。仿真结果表明系统能够实现角度范围为±13.25°的光束偏转。国内首次提出运用Wollaston棱镜来实现大角度的光束偏转。
A wide-angle high resolution beam steering system applying in space laser communication is designed. Liquid crystal spatial light modulator（LCSLM） to achieve narrow-angle beam steering is selected, and then multi-stages Wollaston prisms to reach angle-amplified is adopted. The beam steering principle of the LCSLM and the Wollaston prisms is introduced, and the simulation and analysis of the wide-angle high-resolution beam steering system is presented. The simulative results show that this beam steering system can achieve the angle range. It＇s the first time to apply Wol laston prisms in wide-angle beam steering system domestically.
