    摘要: Provided is an optical scanning device including: a mirror portion having a reflecting surface for reflecting incident light; a first actuator that allows the mirror portion to swing around a first axis located in a plane including the reflecting surface of the mirror portion in a stationary state; a second actuator that allows the mirror portion to swing around a second axis which is located in the plane including the reflecting surface of the mirror portion in the stationary state and is orthogonal to the first axis; a pair of first angle detection sensors that output a signal corresponding to an angle of the mirror portion around the first axis, the pair of first angle detection sensors being disposed at positions facing each other across the first axis or the second axis; and at least one processor, in which the processor generates a first angle detection signal representing the angle of the mirror portion around the first axis by adding or subtracting a pair of first output signals output from the pair of first angle detection sensors.

    摘要: An optical scanning device, a driving method of an optical scanning device, and an image drawing system that can suppress a decrease in image quality of a drawn image are obtained.
    A driving controller derives a first shift time that is a shift time used for correcting a generation timing of a first reference signal representing that an angle of a mirror portion around a first axis is equal to a first reference angle, and is a shift time of a point in time when the angle of the mirror portion around the first axis is equal to the first reference angle with respect to a point in time when an output signal of a first angle detection sensor represents that the angle of the mirror portion around the first axis is equal to the first reference angle, based on an output signal of a photodetector.

    摘要: A processor applies a first driving signal having a first driving frequency to a first actuator, applies a second driving signal having a second driving frequency to a second actuator, generates a first angle detection signal by performing first frequency filter processing based on the first driving frequency on an output signal of a first angle detection sensor, generates a second angle detection signal by performing second frequency filter processing based on the second driving frequency on an output signal of a second angle detection sensor, derives a first angle, which is an angle of a mirror portion around a first axis, based on the first angle detection signal, derives a second angle, which is an angle of the mirror portion around a second axis, based on the second angle detection signal, adjusts the first driving signal based on the first angle, and adjusts the second driving signal based on the second angle.
