Abstract
A method for reducing optical distortion within an optical system employing adaptive optics, includes modifying phase of a wavefront of the optical system with a wavefront coding element. Image data of the optical system is post-processed to remove phase effects induced by the wavefront coding element, to reduce optical distortion caused by the adaptive optics and associated with one or more of quilting, stuck actuator and piston error.
