A 100-kilometer fiber optic cable used in the system can effectively replace a linear array of thousands of conventional seismic sensors. The DAS system is extremely precise, capable of detecting ...

we recorded the first eruption with our system. This was a major international collaboration with real-world impact." DAS works by pointing lasers into unused underground fiber-optic cables (like ...

The primary research interest covers a broad range of Fiber optics sensing techniques and optical sensors, devices, systems and signal processing. For more information on our current and past projects ...

demonstrates how DAS sensors at the Reykjanes Peninsula can give the public warnings on lava eruptions up to 30 minutes in advance. The key to this method is in fiber-optic cables that react to ...
