摘要: 基于自适应光学望远镜的成像特性，分析像斑中心亮度最大以及剩余波前误差最小两种情况下望远镜变形镜的最佳子孔径数范围，利用ZEMAX软件对驱动单元正三角形和矩形布局的变形镜波前校正进行仿真模拟，通过对含高速倾斜镜和不含高速倾斜镜两种情况下望远镜的分析，得到600mm自适应望远镜的最佳子孔径数。

Abstract: Base on imaging characteristics of the adaptive optical telescopes, the number of optimum subapertures is defined and analyzed when the brightness of the image spot center is maximal and the residual wavefront error is minimal. The wavefront correction of the deformable mirror with the triangular and rectangular actuator distribution was simulated by ZEMAX. The quantity of the optimum subapertures for the 600mm adaptive optical telescope was derived based on the analysis of the two cases that the adaptive telescope has or has not a fast tilting mirror.
