Improved sound field penetration using piezocomposite transducers
- Krautkramer Branson, Lewistown, PA (United States)
Ultrasonics has found widespread use in industrial and medical applications. Flaw detection, thickness measurement, and diagnostic imaging are just a few of the tools utilizing this technology. All information acquired by the ultrasound system passes through the transducer before being processed and presented to the operator. Therefore, the performance characteristics of the transducer can significantly influence system performance. In a previous presentation the author demonstrated that the incorporation of piezocomposites into transducer design yields a theoretical improvement of 4 to 10 dB in many applications. Prototype transducers constructed exemplified the expected improvements when used on low loss test materials. However, when these same transducers were evaluated on lossy materials, performance improvements greater than 30 dB were recorded. This presentation explains a major reason for this performance improvement.
