Abstract

We describe the use of high birefringence fibre forming a differential path interferometer for heterodyne fibre optic sensing applications. We firstly recover a low frequency strain amplitude of 1µe at 1Hz applied to a fibre Bragg grating sensor demonstrating a noise limited resolution of around 100ne/vHz. Secondly we interrogate a Mach-Zehnder interferometer sensor using the dual wavelength technique to detect a change in the Mach-Zehnder OPD of 200µm.
