研究了一个以四象限光电探测器和快速剪切反射镜为主要功能块的光束精瞄准闭环控制系统。用一个频率和幅度均可调的扰动源模拟目标的漂移对该系统的性能进行了测试,结果表明在较低频率的扰动下该系统有良好的精跟踪能力。同时,结合一个望远镜跟踪系
A beam aiming closed-loop control system with four quadrant photodetectors and fast shear mirrors as the main functional blocks was studied. The performance of this system was tested by simulating the target drift with a disturbance source of adjustable frequency and amplitude. The results show that the system has good tracking ability under low-frequency disturbance. At the same time, with a telescope tracking system
