Claim 19:
20. A method of synchronizing a first oscillation about a first axis with a second oscillation about a second axis, the method comprising:
driving the first oscillation about the first axis using a first drive signal;
driving the second oscillation about the second axis using a second drive signal;
monitoring a first angular trajectory of the first oscillation about the first axis;
monitoring a second angular trajectory of the second oscillation about the second axis;
generating a first position signal that indicates a position of the first oscillation about the first axis based on the monitored first angular trajectory;
generating a second position signal that indicates a position of the second oscillation about the first axis based on the monitored second angular trajectory;
determining a phase difference between the first position signal and the second position signal;
comparing the phase difference to a threshold value to generate a comparison result;
generating a first reference signal having a first frequency and a second reference signal having a second frequency;
synchronizing the first oscillation to the first frequency and synchronizing the second oscillation to the second frequency according to the first reference signal and the second reference signal, respectively;
monitoring the comparison result; and
synchronously triggering 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.
