    Abstract: An illumination device for illuminating at least one spatial light modulator device. At least one light source device with at least one light source illuminates the at least one spatial light modulator device; a light guiding element through which light emanating from the light source propagates; and at least one light decoupling element arranged on top or inside of the light guiding element. The at least one light decoupling element decouples of a wave field of the light which propagating in the light guiding element into the direction of the spatial light modulator device. The light guiding element has a refractive index which is lower than or at least equal to the refractive index of the at least one light decoupling element. The entrance angle of the wave field entering the light decoupling element is determined by the difference between the refractive indices according to a particular equation.

    Abstract: The invention relates to a display device for representing a three-dimensional scene, comprising a light source array, a lenticular system and a data display in this order, but not necessarily immediately following one another, and a corresponding method for representing a three-dimensional scene. The object thereof is to enlarge the observer region of a 3D display in such a way that this simultaneously provides a plurality of observers with the option of perceiving the 3D scene on the 3D display. This is achieved by an aforementioned display device with a multiplexing element, which follows the data display and can be used to distribute light incident from the data display into a plurality of angle segments, and by an aforementioned method, in which, in an additional step, a multiplexing element distributes the light coming from the data display in a plurality of angle segments.

    Abstract: An illumination device for illuminating a spatial light modulator device. Sub-holograms are used for encoding a hologram into the spatial light modulator device. The Illumination device includes at least one light source for emitting light for illuminating the spatial light modulator device and a beam shaping unit. The beam shaping unit provides a flat-top plateau-type distribution of an absolute value of a complex degree of mutual coherence of the light in a plane of the spatial light modulator device to be illuminated. The flat-top plateau-type distribution of the absolute value of the complex degree of mutual coherence has a shape that is at least similar to a shape of the largest sub-hologram used for encoding of object points into the spatial light modulator device.

    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 realizing 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.
