Affordable DPC ultrasonic transducers: design and applications
Edouard G. Nesvijski · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2001
This work present a new design development of transducers with a Dry Point Contact (DPC) waveguiding extensions, which may serve for ultrasonic laboratory and field testing of materials. Their design allows to apply them for a number of cases where ultrasonic testing is believed to be impossible of inaccurate. Mathematical models based on solutions of the partial wave equation for different types of the DPC waveguiding extensions are applied for optimization of their design. Their amplitude-frequency characteristics are computed. Practical aspects of application of the DPC transducers and their advantages are described in this work.
