Abstract:
1. An optical scanning device comprising: an oscillating mirror part including a reflective surface capable of reflecting light emitted from a first light source and a mass adjustment part formed on an opposite surface of the oscillating mirror part to the reflective surface and configured to be capable of reducing a mass thereof by exposure to laser light; a torsion bar part supporting the oscillating mirror part; a driving part configured to torsionally oscillate the oscillating mirror part about the torsion bar part; a housing accommodating the oscillating mirror part, the torsion bar part, and the driving part; and a reflecting mirror part provided in an interior of the housing and configured to reflect laser light emitted from a second light source disposed outside of the housing to expose the mass adjustment part to the laser light.
