摘要：
An optical deflection device for deflecting light by a mirror mounted on the tip of a rod-like torsion spring which oscillates at near resonance frequency. An optical deflection device which produces a large amplitude by exerting control to avoid variation in the natural oscillation frequency of the torsion spring (including mirror) regardless of temperature fluctuation.
