Fibre Optic Monitoring (FOM) - Introduction

Long-term effectiveness, low maintenance, reliability, high accuracy and resistance to various mechanical and geochemical impacts are major requirements on monitoring systems considered during the operational phase of a repository. To meet such requirements, fibre optic monitoring systems, remotely controlled over several decades, could be particularly suitable. DBE TECHNOLOGY is thus developing a range of sensor systems based on fibre optic technology as the basis for monitoring systems for underground disposal sites.


Up to now, the fibre optic sensing systems developed by DBE TECHNOLOGY have been tested in a sedimentary host rock environment. The main objective of these tests is to develop the technology for installing fibre optic sensors in an engineered barrier material, like bentonite or bentonite-sand mixtures, and to demonstrate the operation of the system under relevant in-situ conditions.

The GTS underground facilities are also available to interested 3rd parties for underground testing and research. The GTS offers cost-effective access to a fully developed, well characterised underground research facility with round the year logistical support - please contact Dr. Ingo Blechschmidt, Head of the Grimsel Test Site, for further details.
