A new method for color holography 3D television system using a white light source and three LCD panels

摘要

A new method for achieving 3D TV was developed and tested with very promising results, In this method, holography techniques utilizing a single white light source, instead of the traditional three color laser lights, and three liquid crystal display panels (LCD) were proposed. A metal halide lamp with good specifications in each wavelength of the color components was adopted as the light source. Each of the three color light components required for the reconstruction of an image was extracted by color separation using cold mirrors. The separated color images were then reconstructed by the hologram formed on the LCD panels which is then combined together through the use of a prism to form a single 3D image. Compared with usual reconstruction methods using three color lasers, this new approach using the single white light source seems to have better color clarity and the overall system cost it lower.
