Abstract

Multiple deformable mirrors (DMs) and an array of artificial guide stars have been used to analyze a method for widening the compensated field of view of an adaptive optical telescope. The contribution of an atmospheric region to the cumulative phase distortion is estimated using wavefront sensor (WFS) measurements. The analysis takes into account the effects of measurement noise, WFS spatial bandwidth, and reconstruction of the wavefront from slope measurements for a 2-layer atmosphere.
