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.
