摘要：

The Frequency response of hydrophones using a thin film of piezoelectric polymer of P(VDF-TrFE) as an active element is investigated. An irregularity in the response for which can not be theoretically accounted is always observed. We have verified by means of optical visualization or schlieren method, that the Rayleigh type wave excited on the backing surface of the hydrophone brings a radial resonance and shows a phenomenon of irregularity on the frequency response.
