    Abstract: A phase modulator for the modulation of the phase of circular polarised light which interacts with the phase modulator. The phase modulator has a first and a second substrate, an electrode arrangement and a liquid crystal layer with liquid crystal molecules. The first substrate is disposed adjacent to the second substrate. The liquid crystal layer is disposed between the two substrates. The first substrate has a first surface, and the second substrate has a second surface. The liquid crystal molecules situated next to the first surface are oriented substantially parallel to the first surface. The liquid crystal molecules situated next to the second surface are oriented substantially perpendicular to the second surface. An in-plane component of the liquid crystal molecule orientation can be set within an angular range of about 180°, e.g. between −90° and +90° related to a specifiable central orientation.

    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 methods for computing holograms for holographic reconstruction of two-dimensional and/or three-dimensional scenes in a display apparatus, wherein a scene for reconstruction is broken down into object points and the object points are encoded as sub-holograms into at least one spatial light modulation device of the display apparatus. A reconstructed scene is viewed from a region of visibility. At least one virtual plane of the at least one spatial light modulation device is stipulated on the basis of a real plane of the spatial light modulation device. A computation of sub-holograms is performed in the at least one virtual plane of the at least one spatial light modulation device.
