Holographic projection device for the enlargement of a visibility region

摘要

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.

1. A method for an enlargement of a virtual visibility region for watching a reconstructed scene, comprising:
emitting sufficiently coherent light from at least one light source so as to generate a wave front of the scene being encoded on a light modulator device; and generating a virtual visibility region for watching the reconstructed scene by imaging the wave front into an observer plane, where the virtual visibility region comprises at least two virtual observer windows, which are dimensioned such that the reconstructed scene is watchable without tracking the observer windows if an observer moves in the observer plane, and wherein the visibility region is reproduced using at least one beam splitter element in order to enable multiple observers to watch the reconstructed scene.
