Abstract
A method for controlling operation of a MEMS mirror includes steps for: generating activation pulses for operating the MEMS mirror and generating a window activation signal for current detection, with the window activation signal overlapping with an end of an activation pulse. The method also includes detecting current through a stator or a rotor of the MEMS mirror during the window activation signal and terminating a current activation pulse and the window activation signal in response to detecting a change in the direction of the current through the stator or the rotor of the MEMS mirror during the window activation signal.
