    • To compensate for an inhomogeneous brightness perception in a holographic reconstruction of 3D-scenes (4), a computing means encodes modulator cells of a SLM with a hologram point data pattern. Multiple bundles of rays illuminate the surface of the SLM and an array of focusing elements (21, 23) directs the bundles of rays to an observer's eye positions. Geometrical and optical properties of the array cause dissimilarly affected illumination regions on the SLM surface. The computing means determine parameters which describe the extent of these effects in combination with an expected spatial filtering at the eye pupil of the observer's eyes. Using these parameters, the computing means estimates which local errors of the reconstruction caused by these dissimilarly affected illumination regions will be perceived by the observer when watching the reconstruction, and corrects the hologram point data pattern such that the reconstruction appears at a corrected brightness uniformity level.
    • 为了补偿3D场景的全息重构中的不均匀亮度感知(4),计算装置用全息点数据模式对SLM的调制器单元进行编码。 多束光线照射SLM的表面,并且聚焦元件(21,23)的阵列将光束束引导到观察者的眼睛位置。 阵列的几何和光学性质导致SLM表面上不同的受影响的照明区域。 计算装置确定参数,其描述这些效果的程度与观察者眼睛的眼睛瞳孔上的预期空间滤波相结合。 使用这些参数,计算装置估计在观察重建时由观察者感知由这些不相关的照射区引起的重建的局部误差,并且校正全息图点数据模式,使得重建出现在校正的亮度均匀度 。

    • Disclosed is a color filter with parallel, vertical color strips of the RGB base colors associated with the image separating means, the color strips repeating horizontally within the color filter in periodic fashion. The light modulator contains a sequence of two registered holograms for each base color interlaced into six pixel columns for a left observer eye and for a right observer eye, and the sequence is repeated horizontally in periodic fashion. The periods of the color filter and the hologram are arranged relative to one another with the same degree of expansion, with a color strip and at least two pixel columns with holograms of the base color of the color strip are associated with a separating element.

    • The invention relates to a controllable illumination device for an autostereoscopic or holographic display, which illumination device contains an illumination matrix of primary light sources having at least one luminous element per light source and a controllable light modulator (SLM) and a reproduction matrix. A computer-generated hologram (CGH) illuminated by the primary light sources (11, . . . , 1n) is coded on the controllable light modulator (SLM) and generates, in at least one plane downstream of the SLM, a matrix—reconstructed from the computer-generated hologram (CGH)—of secondary light sources (2) having a secondary light distribution for the purpose of illuminating the reproduction matrix (4) and for the purpose of focussing in light bundles onto each eye of the viewer via an imaging matrix. The CGH is calculated and reconstructed on the basis of the number of and the positions of the viewers and the system parameters. Owing to the reconstruction of the secondary light sources in a plurality of planes, it is possible for the image information of the display to be tracked for the viewers not only in the case of lateral movements but also in the axial direction.
