Abstract: A wavefront correction system using a dual frequency liquid crystal spatial light modulator to vary phase relationships of a wavefront is disclosed. A light beam from the dual frequency liquid crystal spatial light modulator can be split into a reference beam and a plurality of measurement beams to enhance a speed and/or accuracy of phase measurement. A temperature of the dual frequency liquid crystal spatial light modulator can be sensed to facilitate temperature control and/or temperature compensation, so as to enhance the accuracy associated with use of the crossover frequency used to control the dual frequency liquid crystal spatial light modulator.

Abstract: The use of spatial light modulators to steer light beams is disclosed. A dual frequency liquid crystal spatial light modulator can be controlled so as to form a blazed phase grating thereon that effects desire deflection of incident light.

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.

Abstract: The use of spatial light modulators to steer light beams and/or vary a field of view is disclosed.
