Distributed Acoustic Sensing

“We’re excited to welcome globally recognized scientists, leading technology developers in fiber optic sensing, and our valued FOSA members to the historic city of Graz, Austria,” said FOSA member and meeting host Dr. Werner Lienhart.  The event, themed “Fiber Optic Sensing Development, Commerce and the Greater Good” brings technology and industry leaders together for a visionary exchange including technology presentations, networking plus fiber optic sensing-focused laboratory and field tours in and around Graz, Austria, a UNESCO World Heritage site.

Utah Department of Transportation uses fiber optic cable buried alongside the road to monitor roadways in real time by detecting acoustic events in the vicinity of the fiber, like crashes, avalanches, vehicle speeds and travel times

The combination of DTGS with the DAS FEBUS A1 and high frequency DAS (flow, tube vibrations) allows simultaneous and real-time qualification and quantification of leaks in wells.

Distributed acoustic sensing (DAS)…results demonstrate that φ-OTDR can be used to quantitatively measure strain in roads associated with events as small as a dog walking on the surface.

FOSA announced the three winners of its first Innovation and Project Awards, Fotech, Hifi, and Optasense. The award’s presentation to the honorees was made in Washington at the association’s annual member meeting.
