Abstract: A holographic projection system including first, second and third light sources, SLMs, a lens, a combiner and a control module. The first, second and third light sources generate respective light beams. The light beams have respective wavelengths. The SLMs respectively diffract the light beams. The lens is disposed to adjust a divergence angle of one of the light beams, such that diffracted light out of each of the SLMs is at a same diffraction angle. The SLMs encode phase holograms including respective versions of a graphic image based on light generated by the light sources including light output from the lens to provide phase hologram beams. The combiner combines the phase hologram beams to provide a combined phase hologram beam projected for viewing a combined graphic image. The control module encodes a prism hologram on one of the SLMs to align outputs of the SLMs.
