摘要 在大气湍流条件较好而被探测信标光信号极弱的工作条件下 ,自适应光学系统在实际的应用中需要采用子孔径合并的部分校正方式。本文针对云南天文台 1.2 m高分辨率自适应光学系统中的哈特曼 -夏克 ( Hartmann- Shack)波前传感器结构 ,从光子起伏噪声和 CCD像素读出噪声对子孔径内哈特曼光斑质心探测精度的影响的角度 ,对子孔径软件合并和硬件合并两种方案进行了理论分析和计算 。 When the atmospheric turbulence is weak and the detected beacon is faint, adaptive optics system need to work at partial correction with subaperture mergence. Based on the Hartmann Shack wavefront sensor of the 1.2m high resolution adaptive optics system at Yunnan Observatory, two methods of subaperture mergence are studied in this paper on the Hartamann spot centroid error, and some valuable results have been obtained.
