    • The invention relates to a method for generating video holograms for a holographic reproduction device (HAE) with at least one light modulation means (SLM), wherein a scene (3D-S) split into object points (OP) is encoded as a whole hologram (H? SLM ) and can be seen as a reconstruction from a visibility region (VR), which is located within a periodicity interval of the reconstruction of the video hologram. The visibility region (VR), together with each object point (OP) of the scene (3D-S) to be reconstructed, defines a subhologram (SH) and the whole hologram (H? SLM ) is generated from a superposition of subholograms (SH), wherein in a sequence of image contents the difference subholograms (SD) of object points are preferably generated for each picture, differing in regards to the visibility according to the viewer position (VP) in sequential images (P n-1 , P n ) of the sequence. The display device (HAE) comprises means that provide high-quality video holograms in spite of the data amount being significantly reduced.

    • The invention relates to a sweet-spot-unit which focuses light on predetermined places in the area of the sweet-spot. Said unit contains a controllable optical matrix (BM) which comprises a plurality of controllable pixels which are regularly arranged, in addition to a finely structured optical mask (LM) which has a raster structure (r) which is defined by imaging elements (L1,L2,...). In order to produce sweet-spots on any particular and predetermined place, p pixels (1,..,p) are associated in a controlled manner with each imaging element and the actual geometry of the raster structure (r*) of the optical mask (LM*) deviates from the regular structure (r ) due to the defectively formed imaging elements (L1*,L2*,..). According to the invention, the positions of the pixels (1*,..,p*), for generating the sweet-spot, are selected and controlled in such a manner that they ensure the sweet-sports are undistorted compared to the irregular structure (r*) of the optical mask (LM*).

    • The invention relates to an analytical method for computing a video hologram for a holographic reproduction device (HAE) having at least one light modulation means (SLM), wherein a scene (3D-S) split into object points (OP) is encoded as a whole hologram (H?SLM) and can be seen as a reconstruction from a visibility region (VR), which is located within a periodicity interval of the reconstruction of the video hologram. The visibility region (VR), together with each object point (OP) of the scene (3D-S) to be reconstructed, defines a subhologram (SH) and the whole hologram (H?SLM) is generated from a superposition of subholograms (SH), wherein the complex hologram values of a subhologram (SH) are determined from the wave front of the respective object point (OP) to be reconstructed in a modulator region (MR) of the light modulation means, by calculating and evaluating the transmission or modulation functions of an imaging element (OS) formed in the modulator region (MR). The object point (OP) to be reconstructed is located in the focal point of the imaging element.
