Abstract: A method for manufacturing a light scanning system includes a process of assembling a plurality of device structures, each of device structures including a mirror device and a magnet, a process of acquiring, for each of device structures, first data for correcting a change in a deflection angle of the mirror with respect to a change in a frequency of a current signal, and second data for correcting at least one of a shift of the mirror swinging with a first axis from a Y-axis and a shift of the mirror swinging with a second axis from an X-axis, a process of acquiring, for at least one of device structures, third data for correcting a change in a deflection angle of the mirror with respect to a change in an operating temperature, and a process of storing the first, second, and third data in the storage part.

Abstract: A light scanning system includes a mirror device, a magnet, a temperature sensor, and an arithmetic part. The arithmetic part generates first and second current signals based on a first target deflection angle and a first target frequency, a second target deflection angle and a second target frequency, an operating temperature, first data for correcting a change in a deflection angle of a mirror with respect to a change in a frequency of a current signal input to each of first and second drive coils, second data for correcting at least one of a shift of the mirror swinging with a first axis from a Y-axis and a shift of the mirror swinging with a second axis from an X-axis, and third data for correcting a change in a deflection angle of the mirror with respect to a change in the operating temperature.
