Systems for the reproduction of 3D color images on a projection screen or an emissive display using narrowband modulation of monochromatic components of the image have been described with this subject invention. The stated systems include novel solutions of 3D reproduction using narrowband frequencies of light. The following systems have been included: the system of reproducing 3D color images by projection of monochromatic components of the color image created simultaneously, the system of reproducing 3D color images by projection of monochromatic components of the color image created in temporal sequence, projecting 3D color images by using reflection and transmission through interference filters, reproducing 3D color images using displays with narrow spectrum emissive pixels, the system using background optical guide of narrowband light, and the system using narrowband filters arranged in a series with a pixel matrix. The mutual characteristics of all solutions, depending on the construction thereof, are a wide viewing angle, very favorable separation of the left and right channels, and reproduction without flickering. For projections reproductions, the possibility of using any surface as a screen/display exists, including those that are used for 2D projection. For viewing in all reproduction techniques according to the invention, it is possible to use the same passive type 3D glasses, i.e. those that do not contain electronics or batteries, resulting in lighter glasses and a more comfortable wear and simpler maintenance. |
