Hill-climbing adaptive optics wavefront correction system
摘要
利用一个19单元变形反射镜、远场能量集中度探测器和高频振动控制系统,它可以校正静态的和缓慢变化的动态波前误差.实验结果表明该系统可以校正大型激光工程的波前误差,改善其远场能量集中度.
Abstract
A 19-element serial hill-climbing adaptive optics system is introduced. By using a 19-element def ormable mirror, a detector for sharpness of far-field spot and a dither control system,’ it can correct static and vary slow dynamic wavefront error. The hill-climbing control algorithm, experimental setup and correction effect are reported. Experimental result shows that this system can be used in large laser engineering system for wavefront error compensation and far field sharpness improvement.
