Abstract: A holographic display including light sources (LS1, LS2, . . . ) in a 2D light source array, lenses (L1, L2, . . . ) in a 2D lens array, a spatial light modulator (SLM) and a beamsplitter, in which there are m light sources per lens, and the light sources are in m-to-one correspondence with the lenses. The beamsplitter splits the rays leaving the SLM into two bundles, one of which illuminates the virtual observer windows for m left eyes and the other illuminates the virtual observer windows for m right eyes. In one example, m=1. An advantage is 2D-encoding with vertical and horizontal focusing and vertical and horizontal motion parallax.

Abstract: A 3D content generation system comprising a content generating party that generates 2D content and sends that content to a remote intermediary. The remote intermediary processes the content to facilitate subsequent holographic reconstruction and sends the processed content to a holographic display device which locally generates a 3D holographic reconstruction of the content. An advantage is that 2D content may be processed remotely to provide 3D holographic content.

Abstract: The present invention concerns methods and devices for creating and printing variable size and variable resolution holographic stereograms and holographic optical elements using computer rendered images of three-dimensional computer models or using computer processed images. The present invention is an apparatus and method for printing one-step, full-color, full-parallax holographic stereograms utilizing a reference beam-steering system (400) that allows a reference beam (25) to expose a holographic recording material (70) from different angles. The present invention may also utilize a voxel-control lens (500) placed in the path of the object beam (20) and in close proximity to the holographic recording material (70) to control the resolution of a holographic stereogram. The present invention may also utilize interchangeable band-limited diffusers (45) and reference-beam masking plates (65). The present invention incorporates viewing zone techniques to the rendering process for one-step, holographic stereograms to produce animated, one-step holographic stereograms.

Abstract: A method and a device for encoding and reconstructing computer-generated video holograms using a conventional LC display: it provides holographic reconstruction of three-dimensional scenes using electronically controllable pixel in a holographic array (3) with a conventional resolution, and is reasonably free from flickering and cross-talk. Reconstruction is in real time, and for both eyes at the same time, over a large viewing zone. The method takes advantage of an optical focusing means (2) in order to image vertically coherent light emitted by a line light source (1) into viewing windows (8R, 8L) after modulation by the pixel array (3). The holographic reconstruction (11) of the scene is rendered visible from viewing windows (8R, 8L) for both eyes of an observer by way of diffraction at the pixels. According to the invention, the controllable pixels are disposed in vertical pixel columns (15, 16), which encode separate holograms of the same scene for each of the viewer's eyes (R, L), where said holograms are one-dimensional in the vertical direction and horizontally interleaved. An image separation means (7) with separating elements arranged parallel to the pixel columns reveals the respective pixel columns (15, 15' or 16, 16') for one eye and covers them for the other eye.

Abstract: A holographic optical device (2) includes a light-transmissive substrate (2a), a first holographic optical element (Hs), and a second holographic optical element (Hr) that is laterally disposed on the substrate from the first holographic optical element. At least one of the holographic optical elements is a complex diffraction grating that can handle a multiplicity of plane and/or spherical waves arriving from a range of angles, and having a range of wavelengths. Applications for the device include a wavelength division multiplexer/demultiplexer, an image reconstructor, a beam expander/compressor, and a visor/head-up display.
