Abstract
This invention relates to a laser scanning apparatus which raster-scans a laser beam by using an acousto-optic deflector. In this laser scanning apparatus, the laser beam is horizontally scanned by a pair of acousto-optic deflectors. Thus, a laser scanning apparatus can be realized, which is low in noise, excellent in durability, small in size, light in weight and which can display a picture of high quality at high speed.
