摘要

High-resolution phase-contrast wavefront sensors based on optically addressed phase spatial light modulators and micro-mirror/LC arrays are introduced. Wavefront sensor efficiency is analyzed for atmospheric turulence-induced phase distortions described by the Kolmogorov and Andres models. A nonlinear Zernike filter wavefront sensor based on an optical addressed liquid crystal phase spatial light modulator is experimentally demonstrated. The results demonstrate high-resolution visualization of dynamically changing phase distortions within the sensor time response of abut 10 msec.
