Wavefront reconstruction using iterative Fourier transforms
Abstract
A novel algorithm for wavefront reconstruction based on iterative FFT subroutines is presented. The method applies to domains with any arbitrary shape, and can be used to reconstruct wavefronts from wavefront Laplacians obtained directly from extrafocal images. A flow chart of the algorithm is shown.
