Paper Abstract

The weighted parallel generalized projection algorithm is applied in two steps to the control of two deformable mirrors using multiple wavefront sensing beacons to simultaneously increase the compensated field of view while maximizing point spread function uniformity. Wave optical simulation results are presented that indicate that, even in strong scintillation, not only can the size of the compensated field of view be increased, but also the uniformity of the point spread function over the compensated field of view can be improved by augmentation of constraints enforcing point spread function uniformity.
