摘要
云南天文台1.2m望远镜61单元自适应光学系统已经完成升级改造并投入使用。该自适应光学系统主要由倾斜跟踪控制回路、高阶校正回路以及高分辨力成像系统组成。为了提高系统的跟踪精度,倾斜跟踪控制回路由两级倾斜校正回路串联而成,用于校正望远镜的跟踪误差和大气湍流引起的倾斜跟踪误差。高阶校正回路主要由一套哈特曼波前传感器、一块61单元变形反射镜以及一套高速数字波前处理机组成。系统中哈特曼波前传感器的工作波段为400~700nm,系统成像波段为700~900nm。在介绍61单元自适应光学系统各组成部分的基础上,对该系统的性能进行了分析,并给出了实际天文恒星目标的高分辨力自适应光学成像观测结果。
Abstract
The 61-element adaptive optical system for the 1.2 m telescope of Yannan Observatory had been upgraded and in operation for astronomical observation. It is made up of the fine tracking loop,the higher-order correction loop and the high resolution imaging system.In order to improve the low-frequency compensation performance,the fine tracking system,which is used for correcting the vibration error of the telescope and the tip-tilt error induced by atmospheric turbulence,consists of two cascade control loop. The higher-order correction loop consists of a Hartmann-Shack wavefront sensor,a 61-element deformable mirror,and a high speed digital wavefront sensor. The wavelengths for the Hartmann-Shack wavefront sensor and the imaging observation range from 400~700 nm and 700~1000 nm respectively.The 61-element upgraded adaptive optical system for 1.2 m telescope of Yunnan Observatory is briefly described. The performance on the 61-element upgraded adaptive optical system is analyzed. Furthermore,the observational results for the stars are presented.
