Abstract

In order to analyze the performance of phase retrieval wavefront sensor (PRWS), an experimental based on the PRWS method has been built. In this paper, we utilize liquid crystal space light modulator (LC-SLM) to produce single aberration and random aberration, and validate the ability of PRWS measurement for any aberrations. Mathematic model of phase retrieval measurement is constructed based on the diffraction theory, and solved using gradient based optimization algorithm.
