对由37单元OKO变形镜和140单元BMC变形镜组成的双变形镜系统的联合校正算法做了理论分析，通过将两个变形镜的影响函数组合，提出了一种基于影响函数组合及动态修正的校正模型。仿真研究了37单元OKO单变形镜系统，140单元BMC单变形镜系统，37单元OKO变形镜和140单元BMC变形镜组成的双变形镜系统的闭环校正。结果表明：一是基于影响函数动态修正法的校正效果要优于固定修正法，二是双变形镜系统的校正效果要优于任一单变形镜系统。从而可以在现有技术条件下通过提出的算法提高自适应光学系统的校正能力。

A theoretical study of the algorithm of aberration for a double mirrors adaptive optical system including 37-element OKO deformable mirror and 140-element BMC deformable mirror is presented. By combining the influence function of the two deformable mirrors, a method for aberration correction under combination and dynamic optimization of influence function is proposed. An adaptive optical system using a single 37-element OKO deformable mirror, a single 140-element BMC deformable mirror and two deformable mirrors have been numerical simulated. Results show that the residual aberration by the dynamic optimization method is smaller. It also indicates that the close-loop correction performance of double deformable mirrors is better than that of the adaptive optical system with a single deformable mirror. The method under combination and dynamic optimization of influence function can improve the compensation ability of an adaptive optical system.
