Hologram Coupling into a Waveguide

Abstract

A holographic projection system is provided. The holographic projection system includes a first hologram and a second hologram. The holographic projection system is arranged to spatially modulate light in accordance with the first hologram to form a first holographic wavefront and to spatially modulate light in accordance with the second hologram to form a second holographic wavefront. The holographic projection system further includes a waveguide including an input port that includes a first input area arranged to receive the first holographic wavefront and a second input area arranged to receive the second holographic wavefront. The waveguide further includes a pair of surfaces arranged to waveguide the first and second holographic wavefront therebetween. The waveguide is arranged such the first holographic wavefront is combined with the second holographic wavefront after one or more internal reflections of the first holographic wavefront between the pair of surfaces.
