Sažetak
Appropriate transfer of the ultrasound pulse is essential for the ultrasound based materials characterization. In the appropriate set-up, the ultrasonic pulse transfer is realized as the pulse's propagation from the transducer to the buried object to be characterized, and back to transducer again. The signal received is a complex combination of characteristics of both the transfer entity and the characterized object according to Stepanic et al. (2003 and 2004), and Krstelj and Stepanic Jr (2000). Therefore, the transfer entity influence of the ultrasonic pulse should be known in order to enable one to use the ultrasound for buried object materials characterization. That influence could be modeled and the object containing transfer medium appropriately designed. The recently proposed sensing configuration in which piezoelectric specimens of nonconventional shape are integrated in the hand-probe is presented. We show the manufacturing of the first generation sensors, and characterization of the corresponding ultrasonic fields in space-time-intensity coordinates. Specifically, the details of the ionized cluster beam deposition technique as stated by Takagi (1986) that has been employed in order to achieve the desired novel geometrical shapes of the piezoelectrical sensors is presented and discussed (6 References).
