Abstract

The interaction of fibre Bragg grating sensors with ultrasonic acoustic waves in water is investigated in the near field region of a 1-3 piezocomposite transducer. Longitudinal and transverse strain coupling is studied using two different grating designs and high fidelity measurement of the emitted field was demonstrated.
