Abstract
A scanning mirror resonates on a first axis and moves on a second axis at a frequency dictated by a sync signal. The period of movement on the second axis is not necessarily an integer multiple of the period of movement on the first axis. A drive circuit excites movement of the mirror. The drive circuit adds a position offset to the signal that excites movement on the second axis. The position offset is capable of causing the resonant movement on the first axis to scan a substantially identical trajectory for at least a portion of each period on the second axis.
