Abstract

The fiber optic ultrasonic transducer is resistant to electromagnetic interference and is highly multiplexable. Current optical fiber ultrasonic transducers are mainly used in medical imaging and non-destructive testing (NDT). The current ultrasonic transducer excites a weak ultrasonic signal, which limits its application in large area NDT. This work presents a method for the preparation of a large core diameter optical fiber ultrasonic transducer. Through experimental optimization, the transducer was able to excite an ultrasonic signal with a frequency of 0.449 MHz, a pulse width of about 25 μs and a peakto-peak value of 120 mV.
