为了探讨丽江1.8 m自适应光学望远镜在天文或天体物理研究领域的可能应用,使用误差基本标度理论对其性能进行了初步的理论分析。结果表明,一般观测条件下,系统分辨力可以达到近似衍射极限。同时对在其上配置激光导星系统后可获得的性能进行了预测,结果表明,激光导星自适应光学系统将大幅度提高系统的天空覆盖率。

In order to investigate potential applications of the 1.8m telescope equipped with an auto-guiding stellar adaptive-optics system at the Lijiang observational station, we give a preliminary performance evaluation of this adaptive-optics system by using the theory of scaling of residual phase variances proposed by us. The results show that under usual observational conditions the angular resolution of the system is almost diffraction-limited. We also give an analysis of the performance when a laser guide subsystem is equipped on this adaptive-optics system, and our calculations show that the sky coverage will be consequently greatly improved.
