A novel static semiconductor laser digital scanner is proposed and demonstrated. The scanner consists of a monolithically integrated semiconductor laser array and an aspheric convex lens. Laser beams are deflected and scanned digitally by the convex lens with no mechanical action. Extremely high scanning speed can be achieved with this scanner because the scanning speed is in principle limited only by semiconductor laser switching time. Scanning angles of the laser beam up to 400 were obtained for a 10-element semiconductor laser array. The array spacing is 300?m, and an aspheric convex lens with 4.5 mm focal length was used. Intensity profiles of the deflected beam coincide with calculations using the ray tracing method.
