Abstract:
A transparent ultrasound transducer device for multi-mode optical imaging on a target is provided. The device includes a transparent piezoelectric transducer, one or more wires, and an optical lens. The transparent piezoelectric transducer of a first acoustic impedance is configured to receive acoustic waves from the target. The transparent piezoelectric transducer has a first surface and a second surface. The first surface and the second surface are coated with transparent electrically conductive coatings. The optical lens is contacted with and optically coupled to the first surface of the transparent piezoelectric transducer. The optical lens is made of a material with a second acoustic impedance, and the first and second acoustic impedances are substantially similar to minimize an acoustic impedance mismatch such that sensitivity of the device is improved.
