Abstract:
Disclosed herein are devices and methods to generate a drive signal to actuate a MEMS mirror system. A controller can generate the drive signal to comprise a modified square wave voltage waveform comprising a tri-stated portion, an attenuated portion, or a tri-stated and an attenuated portion to suppress a number of harmonics in a response of the MEMS mirror system to the drive signal.
