环形激光光束的波前复原算法比较
COMPARISON OF WAVE FRONT CONTROL ALGORITHM FOR ANNULAR LASER BEAM
【摘要】 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。
【Abstract】 In this paper, the configurations for wavefront sensor subapertures and deformable mirror actuator in cleaning laser beam adaptive optics system have been simulated, and controlling gradients directly、Fried mode and Southwell mode of zonal wavefront control have been compared. Finally the result of the wavefront correcting ability and stability of controlling gradients directly is the best in these three wavefront control algorithms is presented.
