部分校正自适应光学系统的激光导星阵

Laser guide stars for adaptive optical system with partial correction

讨论了斯特列尔(Strehl)比为0.5的部分校正自适应光学望远镜所需要的人造导星数对望远镜口径及大气相关长度r_0的依赖以及子孔径大于r_0时对导星亮度的要求,最后给出在相应条件下产生钠导星所需要的激光能量。

In this article, the number of the artificial guide stars and the brightness of the guide stars used in the partial-correction adaptive optical system with 0.5 Strehl rate(or 0.13 residual rms wavefront error over the subaperture) have been presented. Comparing to the correspondent results of the conventional system, we find that the partial correction system is simple and easy to realize.
