【摘要】 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统对550m距离的一个动态合作目标进行了精跟踪实验,该系统在望远镜跟踪的基础上可以把跟踪精度提高约90％。更多还原

【Abstract】 A precise pointing system, mainly composed of a quarter optic-electronic sensor and fast steering mirror, have been successfully deployed. A vibration source which frequency and amplitude could be adjusted is applied to simulate the vibration of object, and the performance of the system is tested, the results showed that the system can obtain a high precision at rather low vibrating frequency. The system with a telescope tracking system is used to point a vibrating object 550 m away, and the precision raises 90% based on the working of the telescope tracking system.更多还原
