Paper Abstract

A new technique for phase retrieval in non-linear Curvature Wavefront Sensors is presented. Unlike the iterative Gerchberg-Saxton technique, this technique retrieves pupil phase in a single step. It starts by calculating the optical transfer function from several images each with its own known aberration. It then solves for the pupil phase by inverting the process of autocorrelation, which, in effect, produced the optical transfer functions.
