Patent ID: 7535607

Claim:
Device for reconstructing three-dimensional scenes by video holograms, the device having: optical focusing means comprising a plurality of focusing elements, the optical focusing means directing coherent light from light means to the eyes of at least one observer via a single spatial light modulator that is encoded with holographic information of the three-dimensional scene; and a plurality of illumination units for illuminating the surface of the single spatial light modulator, each illumination unit comprising one of the focusing elements, and a light means that emits coherent light such that each of the plurality of illumination units illuminates one separate illuminated local region of the surface of the single spatial light modulator, whereby the focusing element and the light means are arranged such that the light emitted by the light means coincides close to or at the observer eyes, and wherein the spatial light modulator is encoded such that several local regions illuminated by different ones of said plurality of illumination units simultaneously reconstruct the three dimensional scene using the same video hologram being encoded in the single spatial light modulator.
