Abstract:
A transducer is described that includes a substrate configured to be deposited on a solid object, and a transparent medium coupled to the substrate and configured to oscillate at a pre-selected frequency upon receipt of an electrical excitation or a mechanical excitation and to provide a first acoustic wave. The transducer also includes an actuator configured to receive an electrical power, and to provide the electrical excitation or the mechanical excitation to the transparent medium, wherein at least a portion of the solid object is viewable through the transparent medium, and the first acoustic wave is at least partially transmitted through an interface of the transparent medium. A system and a non-transitory, computer-readable medium storing instructions to cause the system to perform a method to use the transducer for generating acoustic waves in a transparent medium are also disclosed.
