Paper Abstract

Atmospheric turbulence affects the direction and shape of laser beam on long distance laser ranging, especially on the Lunar Laser Ranging (LLR). That will result in decreasing the returned photon numbers on ground station when it performs the LLR. It is need to compensate turbulence effects in real-time on the LLR, first for the effects of atmospheric tip-tilt. In this paper, we present the experiment results at Yunnan Observatory 1.2m telescope that use a small area near the retro-reflector array on the moon surface as an expanded source to detect and compute the atmospheric tip-tilt signal in real time.
