Self Referenced Fibre Optic Glass Absorption Thermometer

A novel fibre optic temperature sensor which uses an internally generated fluorescence signal as an input intensity reference channel is constructed. The absorption changes of a sample of doped glass are monitored in the infra red region of the spectrum and a sensitive all optical thermometer is produced, tested over a wide temperature range from -60°C to +200°C.
