Algorithm study of wavefront reconstruction based on the cyclic radial shear interferometer

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.
