Abstract

High sensitivity pressure measurements are reported using two intrinsic optical fibre methods: Fibre Bragg Gratings and Fibre Segment Interferometry. The optical fibres sensors are surface mounted onto a composite membrane and respective sensitivities of 79.2 µɛ/kPa and 65.8 µɛ/kPa have been achieved at resolutions of 0.79 µɛ and 0.04 µɛ.
