Abstract
A device for optically multiplexing a laser beam, having a glass plate construction with an input surface and an output surface, and bearing reflective and semi-reflective coatings arranged so as to optically multiplex an input laser beam entering the input surface, into multiple spatial-coherence reduced output laser beams exiting from the output surface. Through such optical multiplexing, and recombination, the coherence of the resulting laser beam is substantially reduced, as is the power of speckle pattern noise observed at an image detection array detecting an image of an object illuminated by said laser beam.
