Abstract
Embodiments of the disclosure provide a micromachined mirror assembly. The micromachined mirror assembly includes a micro mirror, a first suspended beam, a second suspended beam, a first actuator, and a second actuator. The micro mirror is configured to tilt around an axis. The first suspended beam and second suspended beam each is mechanically coupled to the micro mirror along the axis. The first actuator is mechanically coupled to the first suspended beam and configured to apply a first torsional stress around the axis to the first suspended beam. The second actuator is mechanically coupled to the second suspended beam and configured to apply a second torsional stress around the axis to the second suspended beam. the first torsional stress and second torsional stress have a magnitude difference.
