Abstract:
An electronic device disclosed herein includes a mirror controller configured to generate a drive control signal, with a drive circuit configured to generate a drive signal for a movable mirror based upon the drive control signal. A sensing circuit is configured to sense the drive signal. The mirror controller is further configured to adjust the drive control signal as a function of the sensed drive signal.
