Abstract
A method for operating a micro-electro-mechanical system (MEMS) scanner on a resonant mode frequency is provided. The method includes generating a drive signal for a MEMS scanner. A sensor signal is received from the MEMS scanner. The drive signal is compared to the sensor signal. An accumulated correction signal is generated based on the comparison of the drive signal and the sensor signal. The drive signal for the MEMS scanner is then adjusted based on the accumulated correction signal.
