Hologram Replicator

Abstract

There is disclosed herein a holographic display system having a viewing window. The display system comprises a hologram replicator and a hologram engine. The hologram replicator is arranged to waveguide a holographic wavefront between a pair of reflective surfaces. A first reflective surface is partially transmissive such that a plurality of replicas of the holographic wavefront are emitted therefrom. The hologram engine is arranged to output holograms. Each hologram is configured to distribute picture content of a corresponding picture by angle such that a spatial coordinate in the picture corresponds to an angle in a holographic wavefront formed from the hologram. The hologram engine is further arranged to determine a plurality of sub-holograms of the picture and nullify an area of each sub-hologram. Each sub-hologram corresponds to a different zone of the picture. A size of the nullified area is different for each sub-hologram.
