摘要
LAMOST是我国也是世界上唯一的同时应用薄镜面主动光学和拼接镜面主动光学的望远镜,但望远镜目前的设计要求还只是共焦,还没有很好地开展共面技术的研究和应用。Keck望远镜的共相方法已经得到了成功的应用,在红外波段得到了10m镜的衍射像。参照Keck的算法,开发了一套用于检测拼接子镜前后有一定平移误差时的模拟软件,在LAMOST及以后各大型望远镜的拼接镜面实验装置上应用。结果表明,这个方法是现实可行的。
The LAMOST is the first telescope using active optics on a thin segmented in China and actually in the world. However, the current design of the telescope is still for confocal imaging and does not involve the coplanar technology. The co-phase technology has been successfully applied to the Keck telescope, resulting in the diffraction image corresponding to a 10m mirror in the infrared band. This paper gives a brief description about the algorithm on the Keck and developes a simulation software usable for detecting the piston errors between mirror segments. The software will be applied to the experimental system of active optics on the segmented mirror on the LAMOST. The simulation result shows that the method should be practically applicable.
