摘要： The invention relates to a method for the multimodal representation of image contents on a display unit for video holograms. Said unit comprises at least one or several light sources (LS), an optical system (L), and a spatial light modulator SLM (S) with hologram contents. According to the inventive method, the unit directs the wavefront that an object would emit to the associated eye positions (EP) such that the viewer sees the reconstruction of the scene and different views are presented to the eyes by means of temporal or spatial multiplexing in order to generate the stereo effect. The inventive method is characterized in that the light of the zero order of diffraction is directed to the eye positions (EP) for a holographic representation in a first mode, whereby the viewer sees the reconstructed scene (3D-S), while the non-diffracted light is directed to the eye positions for a direct representation in a second mode, whereby the viewer sees an autostereoscopic and/or a 2D representation (3D-2D) on the SLM. The invention also relates to display units for implementing said method.

The holographic projection device comprises at least one light modulator device, which contains the array of mirror elements, for an enlargement of a reconstruction space for a reconstructed scene. Each mirror element is coupled with at least one actuator. The actuators tilt the corresponding mirror elements and/or displace them axially in at least one direction. Thereby, a wave front for the representation of a reconstructed scene is directly modulated. The holographic projection device comprises an optical system for the projection of the modulated wave front into at least one observer window in an observer plane.

摘要： A holographic projection apparatus and a method is disclosed 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.
