Abstract

A bowl-shaped ultrasonic transducer is proposed for photoacoustic/ultrasonic multimode microscopy. The transducer uses zinc oxide (ZnO) as the piezoelectric material, which has a better electromechanical coefficient than flexible PVDF polymer and ensures the detection sensitivity. The ZnO film is spherically curved realizing self-focusing. It does not require an acoustic lens, consequently avoiding echo interference by the lens. In addition, it can be integrated with optical fibers. The resonant modes of the bowl-shaped ZnO film were calculated using finite element method. A photoacoustic/ultrasonic dual-modality imaging system is under development to adapt to the designed photoacoustic transducer. First test and imaging are carried out using a commercial ultrasonic transducer.
