摘要
分析了自适应光学系统的波前斜率校正效果 ,综合大气湍流扰动和测量噪声的统计特性 ,在最小二乘复原算法的基础上推导得出一种形式简洁、易于实际操作的最优斜率复原算法。在大气湍流波前扰动条件下 ,对这种最优斜率复原算法的补偿效果和工作稳定性进行了计算研究。
The compensation effects of Hartmann sub-aperture gradients in an adaptive optics (AO) system were analyzed. A kind of optimal-gradient reconstruction algorithm was deduced from normal least-square (LS) reconstruction algorithm by considering the statistical characteristics of disturbed wavefront and measurement noise. The optimal-gradient reconstruction algorithm is concise and effective in practice. The compensation effect and the stability were calculated in the condition of atmospheric turbulence.
