ABSTRACT:
A two-dimensional scanning device constructed with first deflector to deflect a collimated beam, second deflector to deflect an incident beam in the direction orthogonally intersecting the deflecting direction of the first deflector, a scanning lens interposed between the first and second deflectors, a scanning plane to focus a scanning beam from the scanning lens through the second deflector, and an expedient to obtain a distortion-free two-dimensional scanning pattern on the scanning plane by rotating the scanning plane around a rotational axis in the direction orthogonally intersecting the deflecting direction of the second deflector in synchronism with rotation of the second deflector.
