Abstract
A holographic projection system includes a display arrangement. The display arrangement includes a display area arranged to display a first hologram of a first picture and to spatially modulate light incident thereon in accordance with the first hologram to form a holographic wavefront. The system further includes an optical system arranged to receive the holographic wavefront and form a relayed image of the first hologram. The system further includes a waveguide that includes an input port arranged to receive the holographic wavefront and a pair of surfaces arranged to waveguide the holographic wavefront therebetween. A plane of the display area is angled such that the relayed image of the first hologram is formed at a first plane, the first plane being parallel with a plane of the input port.
