dc.description.abstractHigh-resolution phase-contrast wavefront sensors based on optically addressed phase spatial light modulators and micro-mirror/LC arrays areintroduced. Wavefront sensor efficiency is analyzed for atmosphericturbulence-induced phase distortions described by the Kolmogorov and Andrews models. A nonlinear Zernike filter wavefront sensor based on anoptically addressed liquid crystal phase spatial light modulator isexperimentally demonstrated. The results demonstrate high-resolutionvisualization of dynamically changing phase distortions within the sensortime response of 10 msec.<P><Center><I>SPIE Proc., High-Resolution Wavefront Control: Methods,Devices, and Applications II, Vol. 4124, pp. 98-109, 2000.en_US
