摘　　要：液晶相控阵既可以在空间激光通信技术建立多点间空间激光通信链路,又能代替压电偏摆镜的精瞄方式。阐述液晶相控阵应用趋势;通过对液晶相控阵中液晶分子电致双折射和多缝衍射光束偏转原理,提出替压电偏摆镜配合终端进行瞄准捕获跟踪的方案;以“一对二”空间激光通信终端为例,提出基于液晶相控阵多点间空间激光通信终端方案和链路工作模式,分析方案优势,并进行未来展望。Liquid crystal phased array can not only establish the space laser communication link between multiple points in the space laser communication technology,but also replace the precision mode of piezoelectric bias mirror.The application trend of liquid crystal phased array is described in this paper.Based on the principle of electro birefringence of liquid crystal molecules and the deflection of multi-slit diffraction beam in liquid crystal phased array,a scheme of aiming,capturing and tracking for piezoelectric biased mirror with terminal is proposed.Taking"one to two"space laser communication terminal as an example,the scheme and link operation mode of multi-point space laser communication terminal based on liquid crystal phased array are proposed,and the advantages of the scheme are analyzed.
