1 March 1974 Lasers For Information Scan And Control
Author Affiliations +
The laser is a highly advanced light source. The light is intense, monochromatic, and coherent. The light beam can be manipulated, controlled, and detected easily. With additional optical elements the beam can be directed, turned off-and-on, and the intensity varied continuously at will. All of these attributes make the laser a promising component for writing on emulsions and films, character recognition, non-impact printing, and quite recently, video recording and play-back. This all leads us into areas of infor-mation processing, storage, and handling never before thought possible.
