Claim 13:
14. An oscillator system, comprising:
a first oscillator structure configured to oscillate about a first axis according to a first oscillation;
a second oscillator structure configured to oscillate about a second axis according to a second oscillation;
a first driver configured to generate a first drive signal to drive the first oscillation of the first oscillator structure, monitor a first angular trajectory of the first oscillator structure about the first axis, and generate a first position signal that indicates a position of the first oscillator structure about the first axis based on the monitored first angular trajectory;
a second driver configured generate a second drive signal to drive the second oscillation of the second oscillator structure, monitor a second angular trajectory of the second oscillator structure about the second axis, and generate a second position signal that indicates a position of the second oscillator structure about the second axis based on the monitored second angular trajectory;
a phase error detector configured to determine a phase difference between the first position signal and the second position signal;
a comparator circuit configured to compare the phase difference to a threshold value and generate a comparison result;
a reference signal generator configured to generate a first reference signal having a first frequency and a second reference signal having a second frequency;
a synchronization circuit configured to synchronize the first oscillation to the first frequency and synchronize the second oscillation to the second frequency according to the first reference signal and the second reference signal, respectively; and
a synchronization controller configured to monitor the comparison result and synchronously trigger a start of the first reference signal and the second reference signal in response to the comparison result indicating that the phase difference is less than the threshold value.
