摘要
介绍了两种不同的波前重构算法及基本原理，并给出了实用的重构算法公式。通过用哈特曼小孔阵列板代替传统的哈特曼－沙克传感器的方法，对“星光Ⅱ” １０Ｗ高功率激光器的波前相位进行了测量和重构，并对两种算法重构的相位进行了比较，得到了一致而令人满意的结果。
Two different phase reconstruct algorithms are described in this paper. The principle and the practical formula of the reconstruct algorithms are mainly described. Using a Hartmann-Shack (HS) plate with hole array instead of HS wavefront sensor, the phase of Xingguang II 1012 W high power laser is measured. And the results of two reconstructed phases are analyzed. The P-V (peak-valley) and RMS (root-mean-square) values are also compared.
