摘要: The present invention is directed to an improvement in a diffractive display suitable for presenting graphic and the like displays. Broadly, a novel embodiment is realized from a holographic diffraction pattern carried by a magnet or element and an electrically energizable coil magnetically coupled with said magnet that is energizable for movement of the magnet. Rotation of the holographic diffraction pattern generates a display using the diffracted light from the holographic diffraction grating. Another novel embodiment is realized from a faceted rotatable element (FRE) having an array of facets each bearing a diffraction grating and a source energizable for rotation of the FRE from a resting station to a viewing station. Rotation of the FRE generates a display using the diffracted light from the diffraction gratings.

摘要: A head-mounted display device comprises a rendering engine configured to generate a hologram representative of a three-dimensional object. The hologram includes depth information that causes the three-dimensional object to be rendered with a focus that is determined by the depth information. The device also includes a spatial light modulator that modulates light from a light source as indicated by the hologram. A switchable hologram comprises multiple stacked switchable gratings. Each of the stacked switchable gratings is associated with one or more resulting exit pupil locations on a viewing surface. The system also comprises an eye tracker configured to map a viewing direction of a user's eye to a viewing location on the viewing surface. A processor is configured to activate a particular switchable grating within the switchable transmission hologram that is associated with an exit pupil location that aligns with the viewing location.

摘要: Techniques for generating 3-D holographic images of a 3-D real or synthetic object scene are presented. A holographic generator component (HGC) can obtain a real or synthetic 3-D object scene. The HGC generates a high-resolution grating, and generates a low-resolution mask based on the 3-D object scene. The HGC overlays the mask on the grating to generate the hologram, which can be a digital mask programmable hologram. The HGC can use the grating as an encryption key, if desired, wherein the mask can be encrypted based on the encryption key. The display component receives the hologram and can generate holographic images, based on the hologram, and display the holographic images using one or more low-resolution displays. The grating and display can be arranged in various formations in relation to each other. A single display can be partitioned into a tile structure for displaying holographic images in the respective tiles.

摘要: Disclosed is a curved surface element (e.g., light bulb, ornament, light pipe, etc.) which has at least a portion thereof (inner or outer surface) covered with a holographic diffraction grating which was constructed to be essentially distortion free on said curved surface, whereby such diffraction grating diffracts light to emit color to the observer. The diffraction grating can take for form of a holographic optical element (HOE) attached to the curved surface or a diffractive holographic optical pattern (HOP) embossed into the curved surface.

摘要: A holographic volumetric display comprises a pattern generation unit (20), a programmable lighting device and a holographic screen (28). The holographic screen contains one or more pre-recorded set(s) of spatially sampled holographic interference patterns (or sub-holograms) each capable of reproducing one or more volume element(s) or voxel(s) (32) in three dimensional space outside the plane of the holographic screen when each sub-hologram is selectively illuminated. A sub-hologram is a sampled hologram of a voxel and sub-holograms in one set are spatially interleaved across the surface of the holographic screen with other sub-holograms. The programmable lighting device may be provided by a color digital projection unit (28) and the pattern generation unit which can illuminate any number of sub-holograms on the holographic screen. In this way, a volumetric display with holographic voxels can be made. The holographic volumetric display can reconstruct three-dimensional moving images in color.
