  • Feedback control for laser discharge system
    Patent number: 4144539
    Abstract: In a xerographic printer wherein an acousto-optic modulator is used to derive a deflected first order beam of electromagnetic power which raster scans a charged photoconductor to leave a selectively discharged latent image area bordered by a discharged border area; power contents of said first order beam is maintained constant by adjusting the efficiency of the acousto-optic modulator with a closed loop electrical control system. The efficiency of the acousto-optic modulator is adjusted only when the beam is scanning the border area of the photoconductor.
