Light scanning system |
摘要 |
A light scanning system causes a light spot to scan a surface at a constant speed. The light scanning system includes a light source radiating a light bundle, a deflector which deflects the light bundle, a line image imaging optical system which images the light bundle on a deflecting surface of the deflector as a line image, and a scanning/imaging optical system which images the deflected light bundle on the surface as a light spot. The scanning/imaging optical system consists of a first aspheric mirror which is symmetric with respect to an axis of rotation and is disposed on the light inlet side and a second aspheric mirror which is anamorphic and is disposed on the light outlet side. The first aspheric mirror has a negative power in the light deflecting direction and the second aspheric mirror has a positive power in the light deflecting direction.
