Abstract: Provided is a holographic display apparatus capable of providing an expanded viewing window when reproducing a holographic image via an off-axis technique. The holographic display apparatus includes a spatial light modulator comprising a plurality of pixels arranged two-dimensionally; and an aperture enlargement film configured to enlarge a beam diameter of a light beam coming from each of the plurality of pixels of the spatial light modulator. The beam diameter of each light beam enlarged by the aperture enlargement film may be greater than the width of an aperture of each pixel of the spatial light modulator.

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: The layered generation of at least one volume grating in a recording medium by way of exposure, the recording medium having at least one photosensitive layer which is sensitised for a presettable wavelength oft the exposure light. Each volume grating is generated in the recording medium by at least two wave fronts of coherent light capable of generating interference, the wave fronts being superposed in the recording medium at a presettable depth, at a presettable angle and with a presettable interference contrast. The depth and the thickness of the refractive index modulation and/or transparency modulation of a volume grating in the recording medium is controlled by depth-specific control of the spatial and/or temporal degree of coherence of the interfering wave fronts in the direction of light propagation.

Abstract: 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.

Abstract: A holographic display device comprises an OLED array writing onto an OASLM, 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 illuminates the OASLM. The OASLM is suitably controlled by the OLED array. An advantage of the device is that it lends itself to compactness.
