Abstract :
A double-pass configured all-fibre Mach-Zehnder interferometric optical filter has been developed and used in a distributed fibre optic sensor for separation of Rayleigh and Brillouin signals. Its superior performance over a single-pass all-fibre Mach-Zehnder interferometer is highlighted by its 15 dB improved rejection of the Rayleigh signal and comparable throughput
