摘要: 提出一种基于循环式径向剪切干涉的波前重建算法。先将畸变波前经径向剪切干涉仪形成的空间相位调制干涉条纹图通过傅立叶变换处理获得对应的位相差分布，再直接采用迭代算法能精确重建原始波前，为ICF系统中复杂畸变波前的在线准确检测提供了可能，并给出了应用实例。Abstract: The article presents a new algorithm of wavefront reconstruction based on the cyclic radial shear interferomerter. The algorithm is a technique that the actual wavefront can be reconstructed directly and accurately from the distribution of phase difference which is obtained from the radial shearing pattern by Fourier transform profilometry. It can help to measure accurately the distorted wavefront of ICF in-process. An experiment is presented to test the algorithm.
