Patent ID: 8462409

Claim:
Holographic projection system comprising: imaging means for imaging video holograms which are encoded on a spatial light modulator means, at least one modulated wave holographically reconstructing a three-dimensional scene on an observer side of a focussing display screen, and a position controller using position information of current eye positions for controlling optical wave tracking means, which are disposed on the hologram side in front of the focussing display screen, such that the modulated light wave front of the modulated wave appears at the desired eye position on the observer side, irrespective of any changes in the current eye position; and controllable wave forming means for optical wave correction of the form of the modulated wave, said controllable wave forming means being disposed on the hologram side in front of the focussing display screen; and computer means controlling the optical behaviour of the wave forming means based on the position information of the current eye position such that the wave forming means compensate aberrations of the focussing display screen, which follows in the direction of wave propagation, and correcting at least phase errors in the light propagation of the modulated wave such that the modulated wave reconstructs the optical appearance of a scene according to the geometry of the original scene which is visible from the current eye position irrespective of the current eye position.
