Abstract
A near-eye display (NED) includes an image replicator and an image combiner. The image replicator is configured for receiving a beam of image light from a source such as an image projector, and splitting the beam into a plurality of second beams of image light. The combiner is configured to relay the plurality of second beams to an eyebox of the NED such that the second beams at the eyebox are laterally offset from one another. The etendue of the NED may be increased by replicating and relaying the image beams.
