Seismic Monitoring With Distributed Acoustic Sensing From the Near-Surface to the Deep Oceans
Journal of Lightwave Technology(2022)
摘要
Distributed acoustic sensing (DAS) delivers real-time observation ofphysical perturbations such as vibrations or strain variations in conventional optical fibers with high sensitivity. The high density of sensing points and large network footprint provided by a single DAS system, along with the availability of a vast optical fiber network already deployed both in land and in oceanic regions, contr...
