An Amplitude-Phase Method for Testing Acoustic Contact of Ultrasonic Transducer

Resumo

A method is proposed for testing the acoustic contact of an angle ultrasonic transducer by measuring the amplitude and phase of an ultrasonic-wave signal received by an additional transducer from the working surface of the acoustic prism. The characteristic oscillograms of the change in the acoustic-contact quality signal as a function of the change in the contact area are provided.
