    摘要： A light modulator is disclosed for representing complex-valued data, comprising an encoding area that has an arrangement of pixels, the phase of which can be controlled. This largely avoids an interfering optical path difference between adjacent pixels or pixel groups when a complex value is encoded in several adjacent phase pixels of the encoding area, the optical path difference varying according to the angle. One respective specific structured delaying layer, which causes the optical path of an incident linearly polarized beam to change according to the angle, is associated with at least one predefined pixel of a group of adjacent pixels of the encoding area. The thickness of the delaying layer is designed such that the modification of the optical path caused by the delaying layer runs in the opposite direction from the angle-related modification of the optical path difference between individual pixels of the pixel group.

    摘要： A device for the production of holographic reconstructions having light modulators is disclosed. The device comprises at least one pixelated light modulator illuminated by at least one light source, and a focusing optical element field arrangement which images the light sources in an image plane after the light modulator. For the reconstruction, only one order of diffraction of the Fourier spectrum of the hologram should be used. The light modulator is provided with an assigned filter-aperture field arrangement which is located in the area of the image plane of the light source images and which has a plurality of aperture openings. Said aperture openings are designed in such a way that they each allow the passage of a prespecified area of the overall dimensions either smaller or the same as a diffraction order of the diffraction spectrum following Fourier transformation and produced from the holographic coding of the light modulator.
