Abstract
An adaptive optical system with local wavefront sensing and control interferometrically determines wavefront phase aberration in an incoming electromagnetic beam and adjusts the reflective surface of a deformable mirror. The system is characterized by wavefront phase sensing local to the deformable mirror and detection apparatus which synchronously detects phase differences between an interferometrically modulated beam and a uniform modulator.
