概要
- 論文の詳細を見る
We propose a contact ultrasonic probe which can distinguish between longitudinal and transverse vibrations. In contrast to a probe which uses a convergent beam, our probe has resolution which is not limited by the wavelength, so it has high resolution even at low frequencies. It is experimentally confirmed that the probe can discriminate longitudinal and transverse vibrations and that it has resolution higher than about 4 mm which is the wavelength of a carrier wave around 1 MHz.
