Abstract
A scanning system includes 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 reference signal circuit including a digitally controlled oscillator (DCO) configured with a DCO period and configured to divide the DCO period into a plurality of equidistant slices and generate a subtiming signal that indicates the plurality of equidistant slices, a first reference signal generator configured to generate a first reference signal having a first frequency based on the subtiming signal, and a second reference signal generator configured generate a second reference signal having a second frequency based on the subtiming signal; and a driver system configured to drive the first oscillation at the first frequency based on the first reference signal and drive the second oscillation at the second frequency based on the second reference signal.
