  • Capacitive angle sensing of electrostatic MEMS mirrors
    Patent number: 12072485
    Abstract: A system includes an optical reflector to reflect the light, the optical reflector having a rotor, a first stator, and a second stator. The system further includes a controller in communication with the optical reflector. The controller is to drive the optical reflector by applying a first actuation voltage to the first stator, and a second actuation voltage to the second stator. Further, the controller is to apply an excitation voltage to the first stator. Furthermore, the controller is to determine a relationship between a first capacitance between the rotor and the first stator, and a second capacitance between the rotor and the second stator. Based on the relationship, the controller is to determine a position attribute of the optical reflector.
