Paper Abstract

A variety of clever pre- and post-detection methods have been developed to image through atmospheric turbulence. These methods have been developed and exercised primarily for use in the isoplanatic (space-invariant) imaging case. Multi-conjugate methods have been investigated for the accommodation of space-variance with compensated imaging, however multiple guidestars, wavefront sensors, and deformable mirrors are required making a practical implementation uncertain. Post-detection correction methods can be extended to the space-variant case with mosaicing methods, but such approaches provide suboptimal estimates.
