V4 : LOFIGH – Long range Optical Fiber Instruments for monitoring high-level Geohazard in Harsh environment
> Read the articles connected to the projects.
In the follow-up of our instrumental R&D at IPGP and ESEO, which made us demonstrate the performance and interest of high resolution optical seismometers interrogated at the end of pluri-kilometric optical fibers, we propose to develope other innovative optical instruments (hydrophones, strainmeters, tiltmeters, etc…) for remote installation in harsh environment, far offshore as well as on volcanoes, in particular targetting the Seismological and Volcanological Observatories of IPGP (Antilles, La Réunion, Mayotte).
