Claim:
1. An apparatus comprising: a laser producing 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; an angle-magnifying optical element, said at least one second beam splitter reflecting the at least one ideal input beam through said angle-magnifying optical element to generate at least one distorted input beam; a focal plane array receiving said first reference laser beam and said at least one distorted input beam and recording at least one interference pattern generated by said first reference laser beam and said at least one distorted input beam; and a spatial light modulator generating said at least one recorded interference pattern recorded by said focal plane array and receiving said reference laser beam to generate at least one time-reversed output beam; said spatial light modulator transmitting said at least one time-reversed output beam through said angle-magnifying optical element.
