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.

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, comprising:
- decomposing the scene into object points and encoding in a hologram, which is subdivided into subholograms, in the spatial light modulation device,
- encoding object points into encoding regions on the spatial light modulation device, and
- selecting a size and/or shape of the encoding region 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.
