Abstract
This paper describes the design of a wideband acoustic source made of piezoelectric polymer (PVDF) material. The source was especially developed for the absolute calibration and characterization of ultrasound hydrophones. The instruction details and performance characteristics of the wideband PVDF transmitter including its transmitting voltage response and directivity patterns are described; it is shown that the PVDF transmitter allows characterization to be performed as a continuous function of frequency in the frequency range up to 40 MHz. In comparison with the traditional piezoelectric ceramic acoustic sources, the piezoelectric polymer transmitters exhibit improved properties and are well suited for ultrasound dosimetry applications. Their usefulness in measurements based on swept frequency excitation is also pointed out.
