  • ACOUSTO-OPTIC DEFLECTOR WITH MULTIPLE TRANSDUCERS FOR OPTICAL BEAM STEERING
    Publication number: 20150338718
    Abstract: An acousto-optic deflector with multiple acoustic transducers is described that is suitable for use in substrate processing. In one example a method includes transmitting an optic beam through an acousto-optic deflector, applying an acoustic signal with a phase delay across multiple transducers of the acousto-optic deflector to deflect the beam along a first axis by the acousto-optic deflector, and directing the deflected beam onto a workpiece.
