  • Multi-beam scanner with acousto-optic element for scanning imaging surfaces
    Patent number: 5796511
    Abstract: A multi-beam scanning system for scanning a curved imaging surface includes at least one radiation emitter configured to emit a first beam of radiation and a second beam 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. At least one acousto-optic element, disposed in the path of at least one of the beams and upstream of the spin deflector, is operable to deflect the at least one beam with respect to the spin axis of the spin deflector.
