Sub-aperture stitching method to measure aspherical mirror in phase retrieval

A sub-aperture stitching method to measure aspherical mirror in phase retrieval is presented. Analytical expressions for the gradient of a squared-error metric with respect to the object and sub-aperture parameters are obtained. Then we give the sub-aperture stitching algorithm in phase retrieval to...
