Synchronization of microelectromechanical system (MEMS) mirrors

An oscillator system, comprising:

• an oscillator structure configured to oscillate about a first axis according to a first oscillation and oscillate about a second axis according to a second oscillation;
• a first driver configured to drive the first oscillation of the oscillator structure, receive a first measurement signal representative of an entire angular trajectory traversed by the oscillator structure throughout its first oscillation, detect first crossing events of the oscillator structure at which a value of the first measurement signal is equal to a first predefined value that corresponds to a predefined displacement angle of the oscillator structure with respect to the first axis, and generate a first position signal that indicates each of the detected first crossing events with a signal transition;
• a second driver configured to drive the second oscillation of the oscillator structure, receive a second measurement signal representative of an entire angular trajectory traversed by the oscillator structure throughout its oscillation, detect second crossing events of the oscillator structure at which a value of the second measurement signal is equal to a second predefined value that corresponds to the predefined displacement angle of the oscillator structure with respect to the second axis, and generate a second position signal that indicates each of the detected second crossing events with a signal transition;
• and
• a synchronization controller configured to receive the first position signal and the second position signal, and synchronize at least one of a phase or a frequency of the first oscillation of the oscillator structure with at least one of a phase or a frequency of the second oscillation of the oscillator structure, respectively, based on the first position signal and the second position signal.
