Abstract

The invention relates to the technical field of manufacturing of a color computer generated hologram, in particular to a transmission method of color computer generated hologram color information, which is characterized by comprising the following steps of: 1) obtaining the tristimulus values Re, Ge and Be of colors in an electronic display color system; 2) converting the tristimulus values Re, Ge and Be of the colors in the electronic display color system into the tristimulus values Rh, Gh and Bh in a color computer generated hologram color system; and 3) converting the tristimulus values Rh, Gh and Bh in the color computer generated hologram color system into the object wave amplitude of the computer generated hologram. By adopting the method, the value of any color in the electronic display color system can be converted into the value of the color in the computer generated hologram color system, the corresponding object wave amplitude for the computer generated hologram code can be obtained, the digitalized color computer generated hologram can be obtained via the hologram code and output via a device, and thus the optically reproducible color hologram can be obtained.

Description

technical field The invention belongs to the technical field of making computational holograms, in particular to a method for transmitting color information of color computational holograms. Background technique In view of the advantages of color computing holography, such as flexibility, convenience, low cost, and extremely on-site artistic expression, color computing holography has become an important technology for realizing 3D display, and it is one of the research hotspots of 3D display at present. Significant progress has been made in the application of dynamic 3D display. As we all know, the color information used in color computational holography is color digital image information, and its color is determined by the color rendering properties of the three primary color materials of the color display, that is, the PAL or NTSC color system. Color hologram reproduction is through diffraction imaging. The color of the diffraction image is determined by the amplitude of...
