| Research Abstract |
We obtained nearly 7 times larger amplitude by combining the developed laminated transducer and an eight-channel burst pulser compared with a conventional transducer system. We also developed special air coupled transducer adding a silicone rubber as the acoustic impedance matching layer leaded to nearly 7 times larger amplitude than that in a conventional measurement.
