Abstract

Probes with composite transducers are a milestone for ultrasonic testing. As demonstrated by the examples, we can take profit from the piezocomposite features of high acoustic efficiency, low crosstalk, low mechanical Q, low acoustic impedance and mechanical flexibility to improve the overall probe performance. Especially, we gain high sensitivity in combination with well damped signals.
