Abstract
A laser scanning system wherein the scanning line is produced by interposing a computer generated hologram and lens between an illuminating laser beam and the plane of the scan line. Three types of scan patterns (one, two and three dimensional), continuous as well as discontinuous, can be realized by utilizing the principles of the invention.
