Abstract
An all optical fibre based sensing configuration designed to measure the changes in differential length of two independent Fabry-Perot cavities at widely separated locations in an environment where strong temperature gradients may exist is demonstrated. Two Fabry-Perot sensing cavities are formed between the cleaved end of a fibre and a reflective surface. The presented technique is based on low coherence tandem interferometry incorporating high coherence interferometry as a calibration measurement.
