摘要： A holographic display system for generating a super hologram with full parallax in different fields of view in the horizontal and vertical directions. The system includes an array of holographic display devices, e.g., spatial light modulators (SLMs), operable to provide a plurality of holographic images of a scene from differing viewpoints of the scene. Each SLM is operated concurrently to output a narrow field of view, elemental hologram. The system includes coarse integral optics combining the holographic images into a single hologram (“super hologram”) viewable in a hologram image plane a distance from the course integral optics. The coarse integral optics combine the holographic images by providing angular tiling of the holographic images, e.g., bending the axes of parallel lenses. In this manner, the field of view, in one direction, of the super hologram is based on the number of holographic display devices provided in the array in one direction.

摘要： Techniques for efficiently generating full parallax 3-D holographic images of a 3-D real or synthetic object scene are presented. A holographic generator component (HGC) can receive a real object scene or generate a synthetic object scene. The HGC can downsample the scene by a defined downsampling factor and generate, from the downsampled scene, an intermediate object wavefront recording plane (WRP) that can be placed in close proximity to the scene. The HGC can expand and interpolate the WRP to generate the holographic images. The HGC can decompose a scene into polyphase image components (PICs), generate a WRP for the image components, sum the WRP of the PICs, and expand and interpolate the WRP to generate holographic images of the scene. The HGC can utilize look-up tables to store and use wavefront patterns of each region of an image to facilitate reducing computational operations in generating the holographic images.

摘要： 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.
