Abstract
A method and system for aligning a spatial light modulator with respect to an imaging device is disclosed. An image of the spatial light modulator can be formed upon the imaging device and a controller can be used to position optical elements in a manner that effects translation, rotation, and scaling of the image so as to provide desired alignment. Such alignment can, for example, facilitate enhanced wavefront correction so as to at least partially compensate for the detrimental effects of atmospheric distortion in such applications as optical communications, imaging, and weaponry.
