Abstract
In the present invention, by providing a 3D holographic display system comprising a modulation apparatus configured to modulate light emitted from a light source into a light wave corresponding to a 3D image, an optical apparatus configured to propagate the light wave into the first plane, and a diffraction apparatus configured to multiplex the propagated light wave to extend viewing angle of the 3D holographic display, a limited viewing zone of the holographic display determined by the SLM pixel pitch, may be extended by optical methods, such as using diffractive optical elements (DOE) for spatial-division multiplexing (SDM).
