Perfoamance of a high-resolution wavefront control system using a liquid crystall spatial light modulator

摘要

We have developed a high-resolution wavefron control system based on an optically addressed nematic liquid rystal spatial light modulator with several hundred thousand phase control points, a Shack-harmann wavefront sensor with two thousand subspertures, and an efficient resonstruction algoprithm using Fourier transform techniques. We present quantitative results of expeirments to characterize the performance of this system.
