Abstract:
An optical scanning device is provided with a scanning unit including an oscillating element which is elastically and rotatably supported so as to rotatably oscillate, a light beam incident on the scanning unit being deflected to scan as the oscillating element oscillates, a scanning signal generating unit which generates a scanning signal, the scanning signal including a sawtooth wave part and a corrective wave part which is formed based on a resonance frequency intrinsic to the scanning unit, and a driving unit which drives the scanning unit to oscillate the oscillating element in accordance with the scanning signal.
