Abstract

An interferometric technique is demonstrated which allows simultaneous measurement of strain and temperature applied to the same piece of highly birefringent fibre. Second order effects are shown to be important for long sensing lengths or in the presence of high strains or temperature changes. We also describe the results of experiments carried out to verify our theoretical predictions.
