1. A scanning microscope, comprising:

  • a probe having a probe tip for contacting a specimen;

    a stage configured to provide a selected probe tip-specimen displacement;

    a first acoustic transducer coupled to the probe;

    a resonant cavity acoustically coupled to the probe tip;

    a second acoustic transducer acoustically coupled to detect acoustic waves in the resonant cavity; and

    a first transducer driver configured to produce an acoustic vibration of the probe tip with the first acoustic transducer at a probe tip frequency, wherein the resonant cavity dimensions are based on the probe tip frequency.
