| 摘 要： | 在自适应光学系统中,目标跟踪误差主要由未完全补偿的大气湍流扰动和望远镜抖动引起的跟踪误差以及系统的倾斜噪声误差两部分组成。提出一种用闭环残余倾斜数据计算倾斜噪声误差、大气湍流扰动和望远镜抖动引起的跟踪误差以及系统跟踪残余误差的新方法,并用此方法分析61单元自适应光学系统中精跟踪回路的性能。

| Abstract: | In an adaptive optical system,the object tracking error primally censists of the tracking error induced by the incompletely compensated atmospheric turbulence and the telescope vibration and the tilt noise error.A new method with the use of closed-loop residual tilt data is proposed to evaluate the tilt noise error,the tracking error due to the atmospheric turbulence and the vibration of the telescope,and the residual tracking error.This method is used to analyze the fine tracking loop performance of the 61-element adaptive optical system. |
