ABSTRACT:
A system for scanning a surface includes a radiation emitter configured to emit at least one beam of radiation, and a rotating deflector for deflecting the beam(s) onto a scanning surface. The deflector is movable along a translation axis to modify the path of the deflected beam(s) and thereby correct for any mispositioning of the beam(s) with respect to the scanning surface.
