3. Conclusion

After an intense initial R&D phase, followed by numerous field demonstrations, RCFO Fiber Optic Sensor Arrays have progressively whetted the appetite of users, and are now deployed worldwide in a very wide range of application fields, often in harsh environments, from underground mines to spacecraft, transportation, energy, intelligent structures and security. The primary, secondary and tertiary sectors of the economy are all concerned by these innovative measurement technologies.

In this context, the two most emblematic fields, in market terms, are undoubtedly civil engineering and the oil industry, where there is a real need for monitoring, particularly for measurements that cannot be carried out using traditional technologies, either because of severe environmental conditions, or because of the new functionalities offered by optical fibers, at costs that...
