摘要： Two-dimensional scanning apparatus scans a stationary two-dimensional surface with a first deflector and a second deflector which deflects a light beam in a direction perpendicular to the deflecting direction of said first deflector. An afocal optical system is provided between said first and second deflectors, while an imaging lens system is provided between said second deflector and the scanning surface.
