A novel algorithm for high precision wavefront correction in adaptive optics is proposed in this paper. The process of the new global optimization distribution algorithm (GODA) is detailed described and compared with the existing stochastic parallel perturbation algorithm (SPPA). A deformable mirror (DM) group that could realize the algorithm is also introduced. It is made up of a number of single-actuator DMs. In the DM group, each actuator could have three dimensional movements—deformation in z direction and movements in x and y directions, making the equivalent actuator arrangement alterable. Simulations are carried out to verify the correction ability of the new algorithm realized by DM group. By comparing correction results of conventional DM, DM group with SPPA and GODA, the correction ability of DM group with GODA is proved to be better than SPPA and conventional DM.

由可变形镜组实现的全局致动器分配算法，用于激光光学系统中的高精度像差校正

提出了一种新的自适应光学高精度波前校正算法。详细描述了新的全局优化分配算法（GODA）的过程，并将其与现有的随机并行摄动算法（SPPA）进行了比较。还介绍了可实现该算法的可变形反射镜（DM）组。它由许多单执行器DM组成。在DM组中，每个执行器可能具有三维运动-z方向的变形以及x和y方向的运动，从而使等效的执行器布置可变。通过仿真验证了DM Group实现的新算法的校正能力。通过比较传统DM，DM组与SPPA和GODA的校正结果，
