Abstract:
1. An electroholographic display system for displaying a holographic image, comprising: a coherent light source adapted to produce a coherent, collimated, unpolarized light beam; a spatial light modulator (SLM) adapted to receive and spatially modulate the coherent, collimated, unpolarized light beam to produce therefrom a spatially modulated light beam including first portions having a first polarization and second portions having a second polarization orthogonal to the first polarization; and a processor and driver unit adapted to generate hologram data representing a holographic image and to apply appropriate voltages to the pixels of the SLM to cause the SLM to modulate the coherent, collimated, unpolarized light beam with a fringe pattern of the hologram data, wherein the fringe pattern is used to drive the applied voltages to the individual pixels of the SLM, wherein the spatially modulated light beam is projected to an image plane to produce the holographic image including the first portions having the first polarization and the second portions having a second polarization orthogonal to the first polarization, wherein the first portions and second portions have substantially the same amplitude modulation at the image plane.
