Patent ID: 8405891

Claim:
Holographic reconstruction system for the three-dimensional reconstruction of object light points of a scene, comprising: Spatial light modulator means, which modulate light waves which are capable of generating interference and which are emitted by illumination means with at least one video hologram, Optical focussing means which focus the light waves with the reconstructed object light points on at least one eye position of observer eyes, and Electro-optic deflection means which are controlled by a system controller to direct the focussed, modulated light waves with the reconstructed object light points at at least one eye position, and which track them accordingly when the eye position changes, wherein the controllable electro-optic deflection means are an array of deflection means with electronically addressable micro-cells, which has such a periodic structure in a cell grid that the separately controllable micro-cells realise the function of a controllable diffraction grating with variable surface relief structure under coherent illumination, where the system controller changes the optical diffraction behaviour within diffraction orders in a diffraction spectrum of the surface relief structure.
