Abstract

Using a high peak power, narrow linewidth pulsed source coupled with a low loss interferometric fibre optic filtering system, an accurate method of resolving the Brillouin intensity and frequency shift variations in optical fibres for simultaneous distributed strain and temperature sensing is demonstrated for a range of 15km.
