This paper introduces a large-scale distributed fiber optic sensing (DFOS) network inside the tunnel lining of a highway tunnel currently under construction in Austria
Trends in Structural Health Monitoring for the Oil and Gas Market on-demand webinar
GMS receives the best paper award at the 10th International Conference on Structural Health Monitoring: Autonomous Integrity Monitoring of Shotcrete Tunnel Linings using Distributed Fiber Optic Sensing.
researchers at NEC have shown it is possible to monitor traffic using “lit” fiber after separating out sensor and telecom data. Giovanni Milione of NEC Laboratories America, and colleagues used such fiber in Dallas and New Jersey to record the speed of cars as accurately as can be done with cameras
DFOS technologies are evaluated and compared for their ability to monitor the dynamic structural behavior of a model wind turbine tower subject to free and forced vibration. They are further tested for their ability to detect structural phenomena associated with loose bolts and material damage
