针对环形激光光束净化自适应光学系统中的波前传感器子孔径与变形反射镜驱动器布局，仿真比较了直接斜率法、区域法的Ｆｒｉｅｄ模式和Ｓｏｕｔｈｗｅｌ模式三种波前复原算法，其中，直接斜率法的波前校正能力及稳定性均为最好。
Aiming at the wave front sensor subaperture and the deformable mirror driver layout in a ring laser beam self-adaptive optics system, the direct slope method, the Fried method of the area method and the Southwel mode are compared. The direct slope method The wavefront correction and stability are the best.
