Abstract

We detect high frequency ultrasound using in-fibre Bragg gratings using a heterodyne signal recovery scheme. Anomalies in the response of the system due to longitudinal compressional waves in the fibre are investigated and improvements in the system performance are described. The use of shielding materials to reduce the spurious signals due to the ultrasonically induced compressional waves is reported.
