1. A method of scanning a light beam in response to a synchronization signal, comprising the steps of:

  • receiving the synchronization signal having a synchronization frequency;

    activating a resonant MEMs device for periodic movement at a resonant frequency;

    detecting the resonant frequency of the MEMs device;

    synchronizing the MEMs device to the synchronization signal by varying the resonant frequency of the MEMs device; and

    scanning the light beam with the resonant MEMs device at the varied resonant frequency.
