A multiplexed CW Brillouin system for precise interrogation of a sensor array made from short discrete sections of optical fibre

By J.P. Dakin, S. Chin and L. Thévenaz


A novel configuration for precise temperature sensing in an array of optical fibre sections is reported. The sections are chosen to have different Brillouin shifts, to enable separation of scattered light signals in the frequency domain, rather than the traditional time domain, allowing lower-noise CW operation and greater precision due to the 100% duty cycle
