Abstract:
1. An apparatus comprising: a plurality of N column reflectors to receive and reflect an input electromagnetic beam having temporal coherence, wherein the plurality of column reflectors are positioned along a first axis of the electromagnetic beam and at different depths along a path of the input electromagnetic beam, such that each reflector is to reflect different subsections of the electromagnetic beam and temporally differentiate each of the subsections from other subsections of the electromagnetic beam; and a plurality of M row reflectors to reflect the subsections of the input electromagnetic beam, wherein the plurality of row reflectors are positioned along a second axis of the input electromagnetic beam and at different depths along the path of the input electromagnetic beam, such that each reflector is to reflect different sub-beams of each of the subsections and temporally differentiate each of the sub-beams from other sub-beams of other subsections of the input electromagnetic beam; wherein the plurality of row reflectors and the plurality of column reflectors are to generate an output electromagnetic beam having temporal incoherence and comprising an N by M grid of the sub-beams such that each of the sub-beams is temporally differentiated from all of the other sub-beams.
