Apparatuses and methods for controlling a micro-mirror are provided. In one example, a controller is coupled with a micro-mirror assembly comprising a micro-mirror, an actuator, and a sensor. The controller is configured to: receive a reference signal including information of a target oscillatory rotation of the micro-mirror; receive, from the sensor, the measurement signal of an oscillatory rotation of the micro-mirror; determine, based on the measurement signal and the information included in the reference signal, a difference between the oscillatory rotation of the micro-mirror and the target oscillatory rotation; receive an input control signal; generate, based on the difference and the input control signal, an output control signal to control at least one of a phase or an amplitude of the oscillatory rotation of the micro-mirror; and transmit the output control signal to the actuator.
