Abstract :
This study reports on the demonstration and characterisation of a short cavity fibre Fabry-Perot resonator (FPR) for the detection of ultrasonic waves propagating through a solid medium over a frequency range of 1 kHz-10 MHz. The proposed sensing device has some outstanding features in terms of simple fabrication technique, frequency response and high sensitivity over a wide frequency range. The response of the surface-mounted FPR sensor showed good agreement with that of a commercially available piezoelectric transducer during ultrasonic excitation.
