Holographic Projection System with Optical Wave Tracking and with Means for Correcting the Holographic Reconstruction

摘要

A holographic projection system with a display screen and an optical wave tracking means for controlling the direction of propagation of a modulated wave uses a position controller and an eye finder. An extremely wide tracking range is realised in the projection system for simultaneous viewing of the reconstruction by multiple observers, which are situated beside one another. The reconstruction of the scene is reconstructed for each eye position of an observer such that the entire scene is visible in the visibility region in a large tracking range with minimal errors. The projection system reconstructs the scene with the help of modulated partial waves. Projection means direct these partial waves with separately holographically reconstructed segments of the scene at the desired eye position through a structure of screen segments which are at least horizontally staggered on the display screen.
