  • METHOD FOR CALIBRATING A PARTICLE SENSOR, PARTICLE SENSOR, AND APPARATUS HAVING A PARTICLE SENSOR
    Publication number: 20230324276
    Abstract: A method for calibrating a particle sensor includes focusing a laser beam on a calibration plane for generating a calibration intensity distribution in the calibration plane. A calibration plate is arranged in the calibration plane. Contrast regions for modulating an intensity of the laser beam are formed on the calibration plate. The method further includes moving the calibration plate and/or the calibration intensity distribution in the calibration plane, recording at least one intensity signal of the laser beam, following passage through the calibration plane, and calibrating the particle sensor by evaluating the at least one intensity signal.
