Abstract:
Disclosed are a light scanning unit and a method of synchronizing the scanning operation of such light scanning unit. The light scanning unit includes a deflection mirror that is driven to oscillate so as to deflect and scan a light beam in a bidirectional scanning path. The synchronization of a scanning operation may be made at least in part in consideration of the direction of flow of the current that is supplied to drive the deflection mirror to oscillate.
