This book considers some of the means available for the generation of ultrasound, with particular reference to nondestructive testing (NDT). The author explains the factors affecting the efficiency of ultrasonic transducers and offers means of improving their performance, showing the reasoning behind his methods, and gives an introduction to non-contacting means of generating ultrasound, with reference to three instruments in common use. The early chapters of the book demonstrate how the operation of a transducer can be affected by the variations in construction which frequently exist between one instrument and another, and provide a useful guide to some possible parameter modifications which will result in better performance. A theoretical basis for the description and modelling of the transducer is given, showing how the effects of any proposed changes in design can be predicted prior to actual construction. The author also attempts to demonstrate, as simply as possible, the reasons underlying the choice of particular values for the various parameters, by reference to three types of transducer: the piezoelectric probe, the electromagnetic acoustic transducer (EMAT) and the laser generation and reception of ultrasound. The latter are non-contacting techniques, chosen with an eye to the future, since neither technique is yet proven in the NDT context, but for which, the author is confident, nondestructive testing applications will eventually be found.
