(a) Schematic illustration of the HW-TSC. The optical fiber was helically wound around a continuous mandrel to function as an acoustic sensor. (b) Photograph of the HW-TSC and the anechoic tank. One ...

Distributed acoustic sensing (DAS) systems represent cutting-edge technology in infrastructure monitoring, capable of detecting minute vibrations along fiber optic cables spanning tens of kilometers.

Fiber Sensys, part of the Optex group, has launched EchoPoint Distributed Acoustic Sensors (DAS) for advanced intrusion detection across the highest security sites. The latest evolution in fiber optic ...

Pipeline contents are typically valuable, volatile, and harmful to the environment if allowed to escape. With them being susceptible to aging, accidental damage, or tampering, the chances of an escape ...

Andreas Fichtner strips a cable of its protective sheath, exposing a glass core thinner than a hair—a fragile, four-kilometer-long fiber that’s about to be fused to another. It’s a fiddly task better ...

Zhongwen Zhan, 36, can trace one watershed moment in his life to a literal earth-shaking event. He was an undergrad student in China when a 9.1 magnitude earthquake ruptured the sea floor in the ...

Fiber optic sensing can help reduce third-party threats Properly specifying and selecting a distributed fiber optic sensing system during a pipeline's design stage and developing a rapid-response team ...
