Distributed fibre optic sensor system for temperature and strain monitoring based on Brillouin optical-fibre frequency-domain analysis
The authors report on the development of a distributed fibre optic monitoring system for detection of strain and temperature along single-mode fibres. The system is based on the Brillouin optical-fibre frequency-domain analysis (BOFDA). In order to bring down costs of the measuring device, the sideband technique has been implemented for the BOFDA analysis. The use of only one low-cost DFB laser has eliminated the effects of any frequency drift and therefore no tunable laser source has been demanded. They present a BOFDA setup offers digital filtering for enhancement of the dynamic range.
