Optical fibre sensors for earth sciences

This paper reviews the technical evolution of optical fibre sensors relevant to earth sciences with particular reference to high temperature measurements. Optimisation of fibre composition and system design to fully realise the potential of these sensors has led to the substantial advances in both distributed and point sensor systems. Applications of these sensors in the field of earth sciences are discussed to provide a deeper understanding of the potential for monitoring geodynamical and chemical processes in areas of high seismic and volcanic risk.
