Claim 14:
15. A method comprising:
providing a light scanner having scanning element, a first actuator comprising a first actuator element and a second actuator element, and a second actuator comprising a third actuator element and a fourth actuator element, the first actuator being configured to rotate the scanning element about a first axis and the second actuator configured to rotate the scanning element about a second axis, wherein the first axis has a first resonant frequency and the second axis has a second resonant frequency;
applying a first test drive to the first actuator element to induce a first oscillation on the first axis;
establishing the first resistance as a resistance of at least one of the second actuator element, the third actuator element, and the fourth actuator element; and
estimating the first resonant frequency based on a measurement of the first resistance during the first oscillation.
