| 摘 要： | 在利用激光导引星的自适应光学系统中，焦距非等晕性是对自适应光学系统性能的主要限制，利用湍流探测配置的孔径滤波函数导出了剩余波前畸变方差．并依此导出了成像系统的有效直径ｄ０，根据昆明和兴隆实测的大气湍流模型对ｄ０进行了计算，说明了校正平移和倾斜对自适应光学系统的重要性。

| Abstract: | The main limit for a laser- guide- star adaptive- optics- system is the focal anisoplanatism. Firstly, based on the filter function of the atmospheric turbulence sensing geometry,the variance of the residual wave- front distortion resulting from focal anisoplanatism was derived, then the effective diameter d0 of the imaging system was derived. d0 was calculated according to the atmospheric turbulence model in Kunming and Xinglong. The calculation shows that the correction of the piston and the tilt is important for the adaptive optics system. |
