Abstract
The invention relates to a scanning optical system of small size, which is constructed of a reduced number of optical elements. A scanning optical system comprises a prism. In forward ray tracing from a light source to an image plane (the surface to be scanned), a light beam from the light source is collimated by a condensing optical system constructed of a first transmitting surface T, a second reflecting surface R and a second transmitting surface T into a substantially parallel light beam, which is then reflected and deflected at a two-dimensional scanner . The reflected and deflected light forms an image through an image-formation optical system constructed of a third transmitting surface T, a second reflecting surface R, a third reflecting (total reflection) surface R and a fourth transmitting surface T for two-dimensional scanning of the surface to be scanned.
