1. A method comprising:
generating, by a first piezoelectric transducer to which a first excitation signal is applied, back side acoustic waves that are transmitted from a back side of the first piezoelectric transducer into a backing material layer;
generating, by a second piezoelectric transducer coupled to a back side of the backing material layer, a first calibration response to the back side acoustic waves; and
generating an interference signal profile based, at least in part, on the first calibration response.
