Abstract:
1. A micro-electro-mechanical system (MEMS) mirror device, comprising: a mirror; a frame rotatively coupled to the mirror so the mirror is rotatable about a first axis relative to the frame, the mirror has a first resonant frequency for oscillating about the first axis; an actuator rotatively coupled to the frame so the frame is rotatable about a second axis relative to the actuator, the second axis being offset from the first axis, the frame with the mirror has a second resonant frequency for oscillating about the second axis; and stationary spring pads rotatively coupled to the actuator so the actuator is rotatable about a third axis, the actuator being operable to rotate only about the third axis, the third axis being offset from the first and the second axes.
