Abstract: 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 includes at least one spatial light modulator including 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.

Abstract: A holographic display with an illumination device, an enlarging unit and a light modulator. The illumination device includes at least one light source and a light collimation unit, the light collimation unit collimates the light of the at least one light source and generates a light wave field of the light that is emitted by the light source with a specifiable angular spectrum of plane waves, the enlarging unit is disposed downstream of the light collimation unit, seen in the direction of light propagation, where the enlarging unit includes a transmissive volume hologram realising an anamorphic broadening of the light wave field due to a transmissive interaction of the light wave field with the volume hologram, and the light modulator is disposed upstream or downstream of the anamorphic enlarging unit, seen in the direction of light propagation.

Abstract: The invention relates to a display device for holographic reconstruction. The display device comprises a spatial light modulator device having combined phase modulating pixels and amplitude modulating pixels, an illumination unit generating sufficiently coherent light and arranged to illuminate of the spatial light modulator device and a reflection plane. The device being arranged such that light enters the spatial light modulator device and passes both the phase modulating pixel and the amplitude modulating pixel of the spatial light modulator device. The light is reflected by the reflection plane in between.

Abstract: The invention relates to a display device, in particular a head-mounted display or a head-up display, for representing a two-dimensional and/or three-dimensional scene. The display device comprises a spatial light modulator device having pixels, and a beam offset device. The spatial light modulator device is illuminatable with light. The beam offset device is configured to be controllable in such a way that the light modulated by the pixels of the spatial light modulator device is laterally displaceable by less than one pixel extent.

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: A projection device is provided for displaying at least one of a two-dimensional and three-dimensional scene or of content. The projection device comprises an illumination device, at least two spatial light modulator devices and an optical system. The illumination device comprises at least one light source for generating a holographic illumination. One of said spatial light modulator devices is designed as spatial light modulator device modulating at least the phase of the light for the holographical generation of illumination patterns. This spatial light modulator device as first spatial light modulator device is followed by a second spatial light modulator device. The optical system is disposed to illuminate the second spatial light modulator device with a predefinable light distribution generated by the first spatial light modulator device.

Abstract: A holographic projection apparatus and a method for magnifying a virtual visibility region, for observing a reconstructed scene with at least one light modulation device and with at least one light source having sufficiently coherent light for generating a wavefront of a scene that is coded in the light modulation device. By means of imaging the wavefront into a viewer plane, it is possible to generate the virtual visibility region for observing the reconstructed scene. The virtual visibility region has at least two virtual viewer windows. In this case, the virtual viewer windows are dimensioned such that the reconstructed scene can always be observed without tracking of the viewer windows upon movement of a viewer in the viewer plane.
