ABSTRACT:
An optical deflection device is used to deflect a light beam, such as a laser beam, and comprises a base member, a movable member having an optical deflection element, and a set of leaf-spring assemblies provided at respective sides of the movable member. Each of the leaf-spring assemblies is interposed between the base member and a corresponding side of the movable member such that the movable member is resiliently and movably supported by the leaf-spring assemblies with respect to the base member. Each of the leaf-spring assemblies is formed from at least three leaf-spring elements arranged at uniformly angular intervals around an elastic-main-axis of the movable member.
