【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。更多还原

【Abstract】 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 Wollaston prisms in wide-angle beam steering system domestically.更多还原
