Patent ID: 8526088

Claim:
Device for reconstructing three-dimensional scenes by video holograms, the reconstructed three-dimensional scene being a three-dimensional light distribution being viewed by an observer, the device having optical focusing means, including a plurality of focusing elements, which directs coherent light from light means to the eyes of at least one observer via a first spatial light modulator that is encoded with holographic information, wherein: the device has a plurality of illumination units for illuminating the surface of the said first spatial light modulator, each illumination unit comprising one of the focusing elements, and a light means that emits sufficiently coherent light such that each of the illumination units illuminates one separate illuminated region of the surface of said first spatial light modulator and thereby generating the three-dimensional light distribution representing the reconstructed three-dimensional scene being viewed by the observer, whereby said focusing elements, said first spatial light modulator and said light means are arranged such that the light emitted by said light means coincides close to or at the observer eyes.
