Wideband Non-Contacting Ultrasonic Transducer

Abstract

An ideal ultrasonic transducer will be one which responds accurately to an ultrasonic waveform. Information contained within the original waveform should be easily obtained from the output of such a transducer. This will require the transducer to have a number of characteristics: i) Wide bandwidth-for some measurements response up to lOMHz is required. ii) High sensitivity-gives the ability to detect defects at a distance.
