Abstract
An electroholographic display system () for displaying a holographic image, includes a coherent light source () producing a coherent, collimated, light beam; a spatial light modulator (SLM) () adapted to receive and spatially modulate the coherent, collimated, 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 light beam with the hologram data. 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.
