Distributed acoustic sensing (DAS) can turn every meter of a fiber optics cable into a vibration or strain sensor....real-world use cases describe the technical reality of tracking vibration along a fiber optic cable,
The future of technology is here: standard fiber optic cables used as continuous sensors for asset protection and monitoring. AP Sensing’s 5th Generation DAS, specifically, utilizes acoustic vibrations along the fiber optic cable in order to detect and precisely locate events
ASELSAN MIDAS-(R)ailway Multi Purpose Intelligent Distributed Acoustic Sensor rewarded with the "Best Innovation Award 2020" in big companies category in 6th ERCI Innovation Awards - using DAS technology to collect acoustic data and analyze it to detect intrusions on the railway
Observing this "backscatter" phenomenon through a technique called Distributed Acoustic Sensing (DAS), the 20 km long cable was turned into a bed of 10,000 motion sensors that could detect seismic activity with picometer precision.
AP Sensing...recently received funding from the Department for Transport as part of Network Rail’s R&D program....sensors will tap into Network Rail’s existing fiber optic cable network using AP Sensing’s Distributed Acoustic/Vibration Sensing
