Remote measurement of temperature distribution using an optical fibre
Remote measurement of temperature distribution using an optical fibre
A new fibre sensor which measures temperature-distribution is proposed. The sensor uses optical-time-domain reflectometry to determine temperature-induced changes in the levels of the backscatter signal. Experiments using liquid-core fibres have demonstrated a sensitivity of 0.018 dBk over distances of more than 100m. The proposed sensor is able to monitor the temperature of over 100 points simultaneously. Solid core fibres have also been used; they exhibit a wide temperature range, but somewhat reduced sensitivity.

Abstract
A new fibre sensor which measures temperature-distribution is proposed. The sensor uses optical-time-domain reflectometry to determine temperature-induced changes in the levels of the backscatter signal. Experiments using liquid-core fibres have demonstrated a sensitivity of 0.018 dBk over distances of more than 100m. The proposed sensor is able to monitor the temperature of over 100 points simultaneously. Solid core fibres have also been used; they exhibit a wide temperature range, but somewhat reduced sensitivity.
