Beam error correction using movable correction element
摘要
A scanning system for scanning an imaging surface includes a radiation emitter configured to emit a beam of radiation directed towards a deflector for scanning the beam onto the imaging surface. A detector detects any misalignment of the beam with respect to the deflector. A driver moves a correction element substantially perpendicular to the beam axis of the correction element to correct for the detected misalignment during scanning of the imaging surface.
