ABSTRACT:
An optical scanning device is provided. The optical scanning device includes an oscillating mirror which has a pair of electrodes and a mirror oscillator, and which deflects a light beam; a driving unit which applies a wave-like driving signal to the pair of electrodes so as to oscillate the mirror oscillator by an electrostatic force corresponding to the driving signal; and an adjusting unit which changes a duty ratio of the driving signal to adjust an oscillation amplitude of the oscillating mirror.
