ABSTRACT:
An optical system for scanning a surface to be scanned in a slit-like form includes an image forming optical system for forming the image of the surface to be scanned, and a scanner for scanning the surface to be scanned disposed between the image forming optical system and a position whereat the image of the surface to be scanned is formed. The scanner varies the direction of the optical axis of the system three or greater odd number times to thereby make the direction of the optical axis incident on the scanner and the direction of the optical axis emergent from the scanner into the same direction.
