Abstract: The invention relates to a method for generating holograms for encoding in a spatial light modulation device for a holographic display for representing a two- and/or three-dimensional scene. The two- and/or three-dimensional scene is decomposed into object points and encoded in a hologram, which is subdivided into subholograms, in the spatial light modulation device. The object points of the scene are encoded into encoding regions on the spatial light modulation device. A size and/or shape of the encoding region is selected in relation to a size and/or shape of a subhologram, assigned to the encoding region, in such a way that crosstalk of higher diffraction orders in a virtual visibility region is reduced.

Abstract: The invention relates to a holographic display device for representing a two-dimensional and/or three-dimensional scene. The holographic display device comprises at least one spatial light modulator device and an optical component. The at least one spatial light modulator device is provided in order to reconstruct the scene and in order to generate at least one virtual visibility region in an observer plane. The optical component is configured with at least two regions that have a different transparency to one another, the value of the transparency respectively lying between 0 and 1. Furthermore, the optical component is arranged in the display device in such a way that it provides filtering, to be carried out at least partially, of a diffraction order spot in at least one diffraction order inside the virtual visibility region.

Abstract: For comfortable viewing of a 3-D scene at various viewing angles, a display having a large tracking range for a variable viewer distance is required. A controllable light-influencing element deflects light in coarse steps in a viewer range. Within said steps, the light is deflected by a further controllable light-influencing element continuously or with fine gradation. The light modulation device is suitable in holographic or autostereoscopic displays for guiding the visibility ranges of the image information to be displayed so as to follow the eyes of the viewers.

Abstract: The invention relates to a head-up display device for representing information in a field of view of an observer. The head-up display device comprises at least one projection device, a deflection device which comprises at least one deflection element at which incident light beams are deflected, a sensor device, and a control device. The sensor device is used for detecting data of at least one test beam which is incident on the deflection device. The control device is used for determining at least one aberration caused by the deflection device and for determining at least one correction signal in real time.

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.

Abstract: The invention relates to a light modulation device for a display device, in particular a holographic display device, for the representation of two-dimensional and/or three-dimensional reconstructed scenes. The light modulation device comprises at least one spatial light modulator comprising modulation elements for modulating incident light and an optical element of known optical characteristics. The light incident on the at least one spatial light modulator is sufficiently coherent. The at least one spatial light modulator and the optical element are combined with one another in such a way that the optical element scatters the unmodulated light emanating from the spatial light modulator into an angular range.
