自适应光学应用于月球激光测距中视场旋转对大气波前倾斜量提取的影响

The Effect of Image Rotating on the Computation of the Wave-front Tip-tilt Error in the Adaptive Optics for the Lunar Laser Ranging

自适应光学技术应用于月球激光测距试验中需要实时针对月面扩展源进行大气波前倾斜量的提取,望远镜在跟踪月亮的过程中存在月面本身相对望远镜的物方视场的旋转以及望远镜自身的运动所引起的像方视场的旋转,本文讨论了望远镜物方视场及像方视场旋转的规律以及其对大气波前倾斜量提取的影响。

The wave-front tip-tih error should be computed in time for the lunar surface when adaptive optics is used in Lunar Laser Ranging. The rotation of the lunar surface caused by the lunar itself and the movement of the telescope will be observed by the CCD camera, and the algorithms that are used for computing the wave-front error will be effected by it. The rule of the lunar surface rotation and the effect on the algorithm are discussed.
