Paper Abstract

Absorption of 1.06pm radiation in neodymium-doped fibre and subsequent anti-stokes fluorescence is observed in neodymium-doped fibre at elevated temperatures. The increase in absorption is used as the basis for a distributed temperature sensor over the range 20-800°C. The temperature dependence of fluorescence at 940nm is used in an optical fibre point temperature sensor.
