An optical fiber scanning system includes: an optical fiber with a magnet； four drive coils configured to apply a drive magnetic field generated using a drive power signal to the magnet； four detection coils configured to output a detection signal in response to variation of a magnetic field； a controller configured to perform feedback control of the drive power signal； a signal output circuit configured to output a drive signal； a voltage-current conversion circuit configured to convert the drive signal to the drive power signal； and a correction circuit configured to output a magnet magnetic field signal by removing the drive magnetic field signal from the detection signal, and the controller controls the signal output circuit based on the magnet magnetic field signal.
