  • Apparatus for multiple beam deflection and intensity stabilization
    Publication number: 20050061981
    Abstract: A multiple beam generator for use in a scanning system, wherein the generator includes an acousto-optic deflector (AOD) which during use receives a laser beam and generates a deflected beam, the deflection of which is determined by an AOD control signal; a diffractive element which generates an array of input beams from the deflected beam; and a control circuit which during operation generates the AOD control signal and varies a characteristic of the first control signal to account for errors in the scanning system.
