A differential demodulation fibre optic strain sensing system adapted to the needs of complex materials or smart structures monitoring is presented. It is based on low-coherence interferometry in standard single mode fibres and has the advantage that it can automatically compensate for temperature-induced variations in the refractive index and thermal expansion of the silica fibres.
