Abstract

The present invention relates to a projection device for holographic reconstruction of scenes, said device comprising at least one light modulator device and at least one light source which emits sufficiently coherent light for the generation of a wave front of a scene, which is encoded in the light modulator device. A Fourier transform (FT) of the light which is emitted by the light source and modulated by the light modulator device is projected by a projection means on to a screen. Further, the wave front which is encoded on the light modulator device is projected by the projection means into at least one virtual observer window in an observer plane. For tracking the observer window according to a change in an eye position of the at least one observer, the inventive device comprises at least one deflection means, which is disposed between the light modulator device and the screen.
