Distributed Acoustic Sensing (DAS) System

Amonics Distributed Acoustic Sensing (DAS) system is a distributed acoustic sensing system which provides high spatial resolution measurement continuously along tens of km optical fiber. The system can be applied to different areas including infrastructure (bridge, railway, building, etc.) monitoring. There are some other specified applications such as earthquake monitoring, pipeline monitoring, geo-hazards, etc. With adjustable measuring parameters such as Laser pulse width, Sample frequency & resolution, etc., our DAS system is also an ideal equipment for research and development purpose.
