摘要：

A simple zonal approach is proposed for estimating phase distribution on large grids. The estimation is based on phase differences that are precisely measured in two orthogonal directions by a lateral-shearing interferometer. It requires only O(N-2) operations for reconstructing a phase distribution on an N X N grid. Computer simulation and experimental results are demonstrated to show the effectiveness of the new algorithm. (C) 1995 Optical Society of America.
