The research seeks to establish the practical viability of a conceptual method for spatially-distributed measurement of the full polarisation properties of a monomode optical fibre. If this viability can be established, it opens the way for distributed measurement of any external parameter which can modify these properties, such as strain, temperature and electric and magnetic fields.The ability to measure the spatial distribution of three components of strain, plus twist and temperature, on extended structures such as oil rigs, aircraft/spacecraft frames, dams, bridges, large buildings etc, is clearly an attractive prospect for the monitoring, control and improved design of critical, extended structures. This method has the potential to provide this information.A variety of fibre geometries, in association with the polarisation information will be explored to achieve this goal. An experimental rig will be set up to assess the accuracies and spatial resolutions with which the measured fields can be determined.Additionally, an assessment will be made of the applicability of the method to the distributed measurement of electric and magnetic fields.
