Claim Text:
1. A holographic image reconstruction apparatus, comprising: a unit configured to receive input signals representing holograms of an object; a plurality of ultraviolet light sources, each configured to generate a corresponding ultraviolet light beam based on a respective one of the input signals and irradiate the ultraviolet light beam on a scanning mirror; the scanning mirror configured to reflect each of the ultraviolet light beams to generate scan beams; a screen configured to surround the plurality of ultraviolet light sources and the scanning mirror and configured to receive the scan beams which are steered at a plurality of angles by the scanning mirror, wherein the screen is coated with a photochromic material and is effective to form the holograms of the object on the screen due to visible light transmittance characteristics of the screen adjusted in response to the scan beams; and a plurality of reconstruction light sources, each configured to irradiate a reconstruction light beam on the screen to reconstruct images of the object.
