Abstract
Abstract This invention is an optical printer that translates and records visual information that can be seen with ambient light in the first generation holographic printing. The invention permits recording of the information to be made into the light sensitive emulsion as a relief. The result is a stereo-optical, multichannel holographic recording of said information. Applications of the invention may include the commercial photography industry, cinematography, medical, passports, drivers' licenses, security entrance control systems, military, point of purchase advertising, publishing and security as well as other uses connected with all relevant existing holographic technology.
