在双变形镜自适应光学系统中，实现全场补偿的关键步骤之一是使得变形镜2上主激光的振幅分布具有信标光振幅分布。
One key step for full field correction is to match the main laser amplitude distribution with beacon amplitude distribution on deformable mirror 2 in two deformable mirror adaptive optics.
对这三种方案的补偿有效性和连续性分别进行了理论研究，结果表明：补偿后，三种方案均能使偏振耦合分光系统对返回信标光的接收效率达到90％以上；
The validity and continuity of these three solutions is numerically simulated, and the results show that all of them can make the receiving efficiency be better than 90% after compensation.
因此必须建立一个能够处理高速数字信号的图像处理系统，来捕获信标光并计算出信标光在面阵中的脱靶量，以满足实时控制系统的需求。
So it's necessary to set up a image processing system to handle the high-speed digital signals, it's used to acquire the beaconing light and compute it's undershot signal.
