Monitoring of Large Structure Using Distributed Brillouin Fibre Sensing
TL;DR: On-site distributed measurements using a sensor based on stimulated Brillouin scattering are presented in this paper, where long fiber length can be used, so that a dense 2D or 3D measurement of strain or temperature can be obtained in large structure.

Sewerage tunnel leakage detection using a fibre optic moisture-detecting sensor system
Kort Bremer,Merve Meinhardt-Wollweber,T. Thiel,G. Werner,Tong Sun,Kenneth T. V. Grattan,Bernhard Roth +6 more
TL;DR: In this article, the design and development of a new fiber optic sensor system for the optical detection of leakages in sewerage tunnels is reported. But the system developed overcomes the disadvantages of the usually employed camera-based inspection systems which are relatively complex and, in addition, require cleaning of the structures to be monitored beforehand.
