A 3-dimensional image display method stores in memory a plurality of interference patterns in bit format, and recursively projects orthoscopic real or virtual holographic images having both horizontal and vertical parallaxes. A 3-dimensional image display system has a cathode-ray tube comprising a screen made of cathodochromic material, an electron beam unit, and a laser unit. The electron beam unit comprises an electron gun and an electron lens for writing the interference pattern on the screen by a scanning electron beam. The laser unit comprises a point source of coherent light and an optical lens for illuminating the screen by an expanded light beam, and for erasing the interference pattern on the screen. This invention relates to 3-dimensional image display method and system, and the principal use of the invention is for dynamic holograms, and for 3-dimensional computer and television video monitors.
