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

The wave-front tip-tilt 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.
