摘要： Apparatus and methods are provided for mass production of transmission holograms onto a continuous web (30) of photosensitive material, one method involving the mounting of a master transmission hologram (34) onto the outside surface of a clear hollow drum (20), the clear hollow drum being rotatable and having means (24) for directing an irradiating wavefront propagated from a radiation source (70) through the master transmission hologram (34) onto a passing recording medium (30) in a predetermined direction, the directing means (24) configured so that said predetermined direction is fixedly maintainable independent of the rotation of the hollow drum (20) and the master transmission hologram (34) mounted thereon. The redirected irradiating wavefront transmitted through the master transmission hologram (34) generates an object beam and a 'zero order' reference beam, said object beam and 'zero order' reference beam combine to form an interference pattern, the interference pattern being recorded on the photosensitive recording medium (30).

摘要： A procedure for displaying Diffraction Specific (DS) Computer Generated Holograms (CGH) includes the provision of a novel diffraction table (DT) modified so as to store a complete decoded fringe for each point capable of being projected into the image volume. When generating a DS CGH the diffraction table is produced that holds data relating to the image to be projected. The prior art stores in this diffraction table a set of hogel vectors that are used to select a set of basis fringes relating to each point to be displayed on the CGH. This means that each basis fringe corresponding to a particular hogel vector must be accumulated together with all the others before a complete fringe is produced. The pre-computation of the fringes as per the current invention singificantly reduces the online processing requirements of producing an image, as the new DT can be produced offline with no knowledge of the image to be displayed.

摘要： A holographic display device (15) comprises an OLED array (12) writing onto an OASLM (13), the OLED array and OASLM forming adjacent layers. The OASLM encodes a hologram and a holographic reconstruction is then generated by the device when an array of read beams (10) illuminates the OASLM. The OASLM is suitably controlled by the OLED array. An advantage of the device is that it lends itself to compactness.

摘要： Disclosed is a multiplexing method and apparatus that allows holograms to be spatially multiplexed with partial spatial overlap between neighboring stacks of holograms. Each individual stack can additionally take full advantage of an alternate multiplexing scheme such as angle, wavelength, phase code, peristrophic, or fractal multiplexing, for example. An amount equal to the beam waist (216) of the signal beam (212) writing a hologram separates individual stacks of holograms. Upon reconstruction, a hologram and its neighbors will all be readout simultaneously. An filter (130,230) is placed at the beam waist (116a,216a) of the reconstructed data such that the neighbors (116b,216b) that are read out are not transmitted to the camera plane (246). Alternatively, these unwanted reconstructions can be filtered out with an angular filter (630) at an intermediate plane in the optical system that has a limited angular passband.

摘要： A holographic stereogram printing apparatus that is able to formulae a holographic stereogram superior in light utilization efficiency and in picture uniformity. The holographic stereogram printing apparatus causes the laser light from a laser light source 31 to fall on a picture display device 41 to illuminate the light transmitted through the display device 41 as object light on a holographic recording medium 30. The holographic stereogram printing apparatus also causes part of the laser light prior to being transmitted through the display device 41 to be illuminated as reference light on the holographic recording medium 30 to form the element holograms sequentially on the holographic recording medium 30. In the holographic stereogram printing apparatus, a light integrator 63 for uniforming the intensity of light incident on the display device 41 is provided on the optical path of the laser light proceeding towards the display device 41.

摘要： A display system comprising a data provider, a phase-only spatial light modulator (SLM) 701 and a second cylindrical lens 750. The data provider provides first data to the SLM, wherein the first data corresponds to a first cylindrical lens implemented as lensing data in holographic data supplied to the SLM. The first cylindrical lens has optical power in a first direction. The spatial light modulator receives the holographic data, wherein the spatial light modulator spatially-modulates the received light in accordance with the holographic data. The second cylindrical lens, which may be a physical lens, receives the spatially-modulated light from the spatial light modulator and performs a one dimensional Fourier transform of the received light in a second direction, orthogonal to the first direction. The arrangement is intended to reduce intense unwanted zero-order (DC order) light from the reconstructed image, such that it is limited to only part 707 of the holographic reconstruction plane 705.

摘要： 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.

摘要： 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.
