Distributed high-temperature optical fiber sensor based on a Brillouin optical time domain analyzer and multimode gold-coated fiber

Abstract: A high-temperature distributed sensor system based on a Brillouin optical time-domain analyzer and a multimode gold-coated fiber is presented in this paper. Distributed measurements of temperatures up to 600 °C are demonstrated with a temperature accuracy of about 10 °C. The system shows a consistent response for repetitive measurements, even considering increasing or decreasing temperature changes. This is the first time to the best of our knowledge that a gold-coated fiber is used for high-temperature distributed measurements in a Brillouin-based system. The proposed solution via the gold-coated fiber allows a feasible deployment in field applications such as industrial scenarios.
