  • Publication number: 20190278225
    Abstract: A three-dimensional light modulator, of which the pixels are combined to form modulation elements. Each modulation element can be coded with a preset discrete value such that three-dimensionally arranged object points can be holographically reconstructed. The light modulator is characterized in that assigned to the pixels of the modulator are beam splitters or beam combiners which, for each modulation element, combine the light wave parts modulated by the pixels by means of refraction or diffraction on the output side to form a common light beam which exits the modulation element in a set propagation direction.

  • Patent number: 8358454
    Abstract: Disclosed is a display for the holographic reconstruction of a three-dimensional scene using means which allow a reduction of speckle patterns. Speckle patterns result in the graining of a holographic reconstruction and worsen the quality thereof. The 3D scene is incoherently superimposed with itself chronologically or spatially in the eye of the observer. The modulated wave fronts of each reconstructed object point of the scene are shifted relative to themselves in the reconstruction beam path and superimposed in the eye of the observer. The shifting may occur one-dimensionally and two-dimensionally. Each object point is multiplied with itself in the eye of the observer in accordance with the number of the shifted wave fronts. The various speckle patterns over which the eye of the observer averages are also multiplied. Speckle patterns are reduced and the reconstruction quality is thus increased in holographic displays.

  • Patent number: 8264756
    Abstract: An apparatus for recording holograms on an optical medium, in particular on an optically addressable spatial light modulation device is disclosed. For this purpose, the apparatus comprises an illumination device for emitting light, an optical medium, an image source having at least one modulation element, and an arrangement of microlenses. In this case, the arrangement of microlenses is arranged at a distance from the optical medium in such a way that the image focal points of the microlenses lie on the optical medium, such that the hologram can be generated on the optical medium.

  • Publication number: 20090219595
    Abstract: The invention relates to an apparatus for transmissively reading out holograms generated by writing light in an optical medium, in particular holograms generated in an optically addressable spatial light modulation device. For this purpose, the apparatus comprises an illumination device for emitting light and an optical system for directing the light from the illumination device onto the optical medium. In this case, the optical system is arranged in the beam path of the writing light.
