| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We developed the original hydrophone with hydrothermally synthesized PZT poly-crystalline film deposited on a reverse surface of a Ti film front layer as protection layer, acoustic receiving layer and GND electrode in order to realize an anti cavitation hydrophone. Our hydrophone could be used in the high intensity ultrasound field with generation of acoustic cavitation such as focal area of HIFU treatment equipment and in a vessel of an ultrasound cleaner without broken. However, we observed the output waveform of the hydrophone without nonlinear distortion in spite of measurement in high intensity ultrasound field like focal area of HIFU treatment equipment. We considered on the cause of above problem by numerical simulation with MASON’s equivalent circuit and one dimensional acoustic transmission model. As results, it was found that the hydrophone with thinner Ti front layer has wider frequency characteristics of receiving sensitivity. We can expect higher fidelity of received waveform with nonlinear distortion and nonlinear harmonic components by using anti cavitation hydrophone with Ti film front layer with thickness thinner than 5um. | |
