摘要：

This paper describes some preliminary results of the ultrasonic generation characteristics of a new ultrasonic transducer, the plasma igniter. Epicentral out-of-plane responses have been measured using a wide bandwidth stabilized Michelson interferometer. An electromagnetic acoustic transducer (EMAT) has been used to measure the longitudinal wave directivity pattern generated by the plasma source and it compares well to those previously published for laser generated ultrasound. The fields of application of the plasma igniter ultrasonic generation source are limited for reasons that will be explained, but its relatively low cost means that it does merit consideration in some cases.
