Patent ID: 8462408

Claim:
Holographic reconstruction system with an optical system exit for a modulated wave field, comprising: (a) optical focusing means for imaging light sources with light waves which are capable of generating interference into a visibility region which lies in front of an eye position, (b) spatial light modulator means, which comprise modulator cells for modulating the wave field with video holograms and for holographically reconstructing object light points of a scene by way of interference of the modulated wave field, (c) a system controller with a hologram processor for re-computing the video holograms and with an eye finder, said system controller directing the light waves at least one current eye position and tracking the light waves accordingly when the eye position changes, where the optical focusing means comprise an array of focusing means with a multitude of focusing elements, and where each light source is assigned to at least one focusing element, thus forming a bundle of illumination units which jointly illuminate the light modulator means, wherein the reconstruction system further comprises electro-optical deflection means, which lie at the system exit, and which comprise at least one array of deflection means with controllable optical cells whose light exit direction can be controlled, so that each light source and each focusing element is assigned to at least one controllable optical cell, the system controller controls the electro-optical deflection means based on position signals which are detected by the eye finder such to serve an eye position which is determined by the content of the active video hologram, so to direct the focused, modulated light waves which are capable of generating interference at the at least one eye position, and the hologram processor controls the phase structure of the deflected propagating modulated wave field by way of accordingly encoding the modulator cells in order to provide a reconstruction of the scene through interference of the modulated wave field.
