Abstract :
We have demonstrated the principles of a distributed optical fibre sensor for monitoring the integrity of large Parafil ropes in offshore applications. It has been shown that by introducing a number of partial reflectors along the fibre, and by interrogation of one particular property of the light, it is possible to detect and locate a short transient signal such as the acoustic emission caused by a yarn snapping. It is envisaged that this type of sensor could be applied to any application where it is desirable to locate and/or identify a transient signal, such as a security perimeter fence or to measure traffic speed
