Abstract
A light projection system includes a microelectromechanical (MEMS) mirror configured to operate in response to a mirror drive signal and to generate a mirror sense signal as a result of the operation. A mirror driver is configured to generate the mirror drive signal in response to a drive control signal. A zero cross detector is configured to detect zero crosses of the mirror sense signal. A controller is configured to generate the drive control signal as a function of the detected zero crosses of the mirror sense signal.
