Abstract:
A micro-oscillation element includes a movable main section, a first frame and a second frame, and a first connecting section that connects the movable main section and the first frame and defines a first axis of rotation for a first rotational operation of the movable main section with respect to the first frame. The element further includes a second connecting section that connects the first frame and the second frame and defines a second axis of rotation for a second rotational operation of the first frame and the movable main section with respect to the second frame. A first drive mechanism is provided for generating a driving force for the first rotational operation. A second drive mechanism is provided for generating a driving force for the second rotational operation. The first axis of rotation and the second axis of rotation are not orthogonal.
