ABSTRACT:
A multi-beam scanning system for scanning a curved imaging surface includes at least one radiation emitter which emits first and second beams of radiation. A spin deflector, rotatable about a spin axis, directs the first beam to form a first scan line and the second beam to form a second scan line on the imaging surface. A deflection element, disposed in the path of the first beam and upstream of the spin deflector, operates to deflect the first beam with respect to the rotation of the spin deflector. The spin deflector is impinged by beams of radiation only at a distance, other than zero, from the spin axis.
