Abstract:
A method and apparatus for simultaneous spatial light modulator beam steering and system aberration correction. The apparatus includes a spatial light modulator, a wide-field optical system, the wide-field optical system including at least one optical system aberration; and a camera. The wide-field optical system collimates a light beam toward the camera. The camera communicates with the spatial light modulator via a feedback loop that pre-corrects for the at least one optical system aberration.
