Application of 1.2m adaptive optics system for astronomy

Abstract

A 61-actuator adaptive optical system has been upgraded at Yunnan observatory 1.2m telescope since 2004, and is only one visible wavelength AO system in China now. Considering its relative small diameter and angular resolution, the main purpose of this AO system, besides the high resolution astronomical imaging, is for long distance laser ranging. This paper describes these AO system performances and its observation results, and the possible application on lunar laser ranging.
