Experiment of Closed-Loop Pointing Errors Compensated by Hill-Climbing Method in Laser Pointing System Using Return Photons
Energy losses on target caused by boresight and jitter are two fundamental pointing errors for a laser pointing system. The characteristics of return photons reflected from an intended target in a laser pointing system are studied and a laboratory device is set up. With the hill-climbing method, a closed-loop laser pointing is realized. Furthermore, the accuracy of this technology is analyzed with different jitters, and effect of jitter on real-time pointing is discussed. The experimental results demonstrate that, the performance of hill-climbing method is still excellent. Moreover, with the increasing of jitter, the sample size of return photons increases, and the pointing precision decreases.
