Abstract
Described herein is a device including mirror control circuitry for controlling a movable mirror. The mirror control circuitry includes drive circuitry for providing a drive signal to the movable mirror, and a processor. The processor cause the drive circuitry to generate the drive signal so as to have pulses with leading edges occurring an offset period of time after a maximum opening angle of the movable mirror and trailing edges occurring an offset period of time before a zero crossing of the movable mirror. The processor may sample a mirror sense signal from the movable mirror at times at which a derivative of capacitance of the movable mirror with respect to time is zero, and then perform an action based upon the samples.
