Patent ID: 7400431

Claim:
Method for encoding and reconstructing video holograms, where optically vertical focusing means image vertically coherent light emitted by a line light source and modulated by electronically controllable pixels of a holographic array into a viewing plane with viewing windows, in order to holographically reconstruct a three-dimensional scene within one diffraction order by way of diffraction at the pixels and to render this scene visible from the viewing windows for both eyes of an observer, wherein the controllable pixels encode two separate holograms of left or right eye perspective views of the same scene in separate pixel columns, one for each of the observer's eyes, said holograms being one-dimensional in the vertical direction, where the pixels are arranged in separate column groups so that the two one-dimensional holograms are horizontally interleaved, and an image separation means with separating elements arranged parallel to the pixel columns reveals the respective pixel columns for one eye and covers them for the other eye.
