Video hologram and device for reconstructing video holograms for large objects
InactiveUS7315408B2Reduce intensityHigh diffractionHolographic light sources/light beam propertiesHolographic object characteristicsComputer graphics (images)Radiology
A video holographic display device operates so that the size of a reconstructed three dimensional scene is a function of the size of the hologram-bearing medium; the reconstructed three dimensional scene can then be anywhere within a volume defined by the hologram-bearing medium and a virtual observer window through which the reconstructed three dimensional scene must be viewed. This contrasts with conventional holograms, in which the size of the reconstructed scene is localised to a far smaller volume and is not a function of the size of the hologram-bearing medium at all.

A method of computing a hologram by determining the wavefronts at the approximate observer eye position that would be generated by a real version of an object to be reconstructed. In normal computer generated holograms, one determines the wavefronts needed to reconstruct an object; this is not done directly in the present invention. Instead, one determines the wavefronts at an observer window that would be generated by a real object located at the same position of the reconstructed object. One can then back-transform these wavefronts to the hologram to determine how the hologram needs to be encoded to generate these wavefronts. A suitably encoded hologram can then generate a reconstruction of the three-dimensional scene that can be observed by placing one's eyes at the plane of the observer window and looking through the observer window.

In a video hologram that enables a three dimensional scene to be reconstructed, a specific region in the hologram encodes information for a particular, single point in the reconstructed scene. This region is the only region in the hologram encoded with information for that point, and is restricted in size to form a portion of the entire hologram, the size being such that multiple reconstructions of that point caused by higher diffraction orders are not visible at the defined viewing position. This contrasts with conventional holograms, in which the information needed to reconstruct a given point is distributed across the entire hologram.
