ABSTRACT:
A two-dimensional scanning apparatus is disclosed which includes first deflector for deflecting a collimated beam, second deflector for deflecting the incident beam in the direction orthogonal to the direction of deflection by the first deflector, a scanning lens disposed between the first and second deflector, a surface to be scanned on which an image of the scanning beam is formed through the second deflector and a device for moving the scanned surface in the direction orthogonal to the surface in synchronism with the rotational motion of the second deflector so as to obtain a two-dimensional, distortionless scanning pattern on the scanned surface.
