Single-mode distributed temperature sensing using OFDR
W. Hill, J. Kübler, M. Fromme, LIOS Technology GmbH (Germany)
Distributed temperature sensing (DTS) using Raman-OFDR is not limited by non-linear effects or low duty cycles in long single-mode fibres. It shows full spatial and temperature resolution at a range of 30km. The availability of hydrogen resistant fibres favours single-mode DTS in applications with chemical load such as oil and gas production.
