Abstract: The invention relates to a display device for holographic reconstruction of two-dimensional and/or three-dimensional objects (1). The objects (1) include a plurality of object points (1a-d). The display device comprises an illumination unit, a spatial light modulator device and a separator. The illumination device emits sufficiently coherent light. Sub-holograms (3a-d) of object points to be displayed (1a-d) are encoded in pixels of the spatial light modulator device. The separator is provided for separating adjacent point spread functions in an eye of an observer generated by the sub-holograms (3a-d) of adjacent object points (1a-d) such that the adjacent point spread functions are mutually incoherent.

Abstract: The invention relates to a method for producing holograms for encoding in a spatial light modulation device for a holographic display for displaying a two-dimensional and/or three-dimensional scene. The two-dimensional and/or three-dimensional scene is split into object points and is encoded in a hologram divided into sub-holograms in the spatial light modulation device. The object points of the scene are encoded in encoding regions on the spatial light modulation device. A size and/or a shape of the encoding region is selected in comparison with a size and/or a shape of a subhologram associated with the encoding region in such a way as to reduce crosstalk of higher orders of diffraction in a virtual visibility region.
