A system for measuring the strain in a structure in which the temperature at the location the strain is measured is also measured in which an optic fiber is incorporated in the structure which has an interferometer positioned at the point or points where the strain is to be measured, a pulse of light is sent down the fibre and the backscattered light is split to separate the RSS light, the interferometer is used to measure the strain and the RSS is used to measure the temperature. There can be a network of fibers to monitor the strain throughout the structure.
