Abstract

Fibre optic sensing devices have been produced for the dual measurement of strain and temperature using the combined properties of fibre Bragg gratings and the fluorescence lifetime of erbium-doped fibre. Two different sensors were constructed with the fibre Bragg grating written in normal fibre and also written directly in the Er 3+ -doped fibre. Results obtained indicate that this technique can be used to measure strains and temperatures with accuracies of approximately 1.2°C and 20.4 με
