<p>A system for sensing changes in a parameter in a structure such as temperature or movement of the structure, in which optical fibres are embedded in the structure, coherent light is passed down the optical fibres and the output of each of the optical fibres combined to form a pattern, changes in the parameter causes changes in the optical path of the light in each fibre which changes the pattern and can be detected and monitored.</p> |
