摘要
从伺服控制系统的角度分析了自适应光学系统的闭环噪声、大气湍流引起的误差以及系统的总体误差，并在此基础上对自适应光学系统的有效性、系统的最佳带宽选取及系统的极限工作能力进行了分析，对已经建立的２．１６米望远镜红外自适应光学系统给出了分析结果曲线。
This paper analyses the closed-loop noise,the error caused by turbulence and the total error of adaptive optics system in terms with servo control loop.Based on the total error,the effectiveness,the optimal closed-loop bandwidth selection and the limited capability of adaptive optics system are also analysed.Furthermore,the analytic result cuves of a practical system,the infrared adaptive optics system at 2.16m telescope, are presented in this paper.
