概要
- 論文の詳細を見る
The construction of piezoelectric polymer film hydrophones has been studied in order to suppress irregularities in hydrophone frequency response and directivity characteristics caused by the formation of induced surface waves on the backing material. A polyvinylidene fluoride (PVDF) hydrophone having a cylindrical baking material rounded at its edge is shown to have flat frequency response in the range of 100 kHz to 10 MHz and to have good directivity in agreement with piston motion theory.
