Non-mechanical digital/holographic wide angle control of one or more lasers beams
Abstract:
An apparatus including a laser generating a plane wave beam, a first beam splitter splitting the plane wave beam into a first reference laser beam and at least one ideal input beam, at least one second beam splitter, and an angle-magnifying optical element. The at least one second beam splitter reflects the at least one ideal input beam through the angle-magnifying optical element to generate at least one distorted input beam. The apparatus further includes a focal plane array receiving the first reference laser beam and the at least one distorted input beam and recording at least one interference pattern generated by the first reference laser beam and the at least one distorted input beam. The apparatus further includes a spatial light modulator generating the at least one recorded interference pattern, receiving the reference laser beam, and transmitting at least one time-reversed output beam through the angle-magnifying optical element.
