Abstract:
1. A three-dimensional holographic image display device comprising: a spatial light modulator (SLM) configured to display holograms for a left and a right eye; a reproducing light source configured to irradiate light for reproducing an image onto the SLM; a lens unit configured to reproduce an image by converting light emitted from the hologram displayed on the SLM; a beam dividing unit configured to divide light incident from the reproducing lens unit so as to proceed along a first path and a second path; a right eye active shutter disposed in a light path between the beam dividing unit and the right eye and substantially synchronized with the SLM to transmit or block light; and a left eye active shutter disposed in a light path between the beam dividing unit and the left eye and substantially synchronized with the SLM to transmit or block light.
