Paper Abstract

A new technique for global wavefront sensing is proposed. This technique is based on the iterative phase retrieval algorithm proposed by Fienup. Shack-Hartmann sensor images are used as an additional constraint in this algorithm. Computer simulation results verified the effectiveness of this method.
