Abstract

The invention provides a method of displaying true colors of a computed hologram synthesized with single pictures by using a white LED as a representation light source. The method comprises a step of manufacturing a synthetic hologram and a step of designing an optical filter with a pixel structure. According to the method for displaying true colors of the computed hologram, firstly, three colored pictures of the same scene are manufactured into a Fresnel hologram in a Burch coding manner; three coded pictures are synthesized into one hologram according to a special structure on the basis of the colored display principle of three primary colors and the recording-representation characteristics of the hologram; and secondly, one optical filter with the pixel structure is designed and the true-color holographic display by using the white LED as the representation light source is realized.

Description

technical field [0001] The present invention relates to computing holographic display technology, more specifically, the present invention relates to computing holographic true color display technology. Background technique [0002] Computational holographic display based on spatial light modulator is a true three-dimensional stereoscopic display technology, which can reconstruct a true stereoscopic image of a three-dimensional scene. The stereoscopic image contains continuous parallax information, and the viewer can view the real scene without wearing auxiliary equipment. feeling, and there is no stereoscopic viewing fatigue. However, when the hologram is reproduced, the principle of light diffraction is used, and the reproduced light must be coherent light with a fixed wavelength. Therefore, the reproduced image has a single color. In order to realize a true-color computational holographic display with better quality, a complex reproduction optical system is required, and...
