阐述了全光路像差校正自适应光学系统的工作原理, 明确了全系统的校正能力受制于角锥棱镜阵列的面形像差。针对工作在0.6328 μm波长的全光路像差校正自适应光学系统, 从仿真的角度研究了3种角锥棱镜阵列, 研究了角锥棱镜阵列的组成单元——角锥棱镜的综合角误差在2″以内时, 角锥棱镜阵列的面形像差可以忽略。用WYKO 干涉仪测量了实际角锥棱镜阵列内每个角锥棱镜的波像差, 根据波像差计算的综合角误差, 拟合了角锥棱镜阵列的面形, 验证了仿真结果。

The principle of the adaptive optics system for all-path aberration correction is presented. And the correction ability of the adaptive optics system for all-path aberration correction is confined by the aberration of the retro reflector array. Three kinds of the retro reflector arrays are numerically simulated for the appointed wavelength adaptive optics system for all-path aberration correction. It is studied that the aberration of the retro reflector array can be neglected while all-angle error of cell of the retro reflector array lies in 2＂. The simulation result is approved by the all-angle error based on the aberration of retro reflector in retro reflector array measured by WYKO interferometer.
