Abstract

We investigate the feasibility of using in-fibre Bragg gratings to measure ultrasonic fields for medical applications. Two signal processing schemes for interrogating the gratings are described. Preliminary results for each scheme (one a homodyne approach, the other a heterodyne one) give noise-limited pressure resolutions of 2.2 × 10^-4 and 1.8 × 10^-2 atm respectively, each within a 1 Hz bandwidth. The second scheme, however, gives a more stable response.
