Adaptive Optics (AO) requires three elements: a Shack Hartmann wave- front sensor, Deformable Mirrors (DM) and computer control to compensate or correct for the distortion of the wavefront caused by turbulence in the atmosphere. These methods are limited by their massive scale, comparable expense and hardware constraints relating to the number of mirror element. We are developing a new approach to astronomical AO which uses an interferometric sensor, phase determination based on wavelet ridge extraction, and phase conjugate distortion correction.
