   Geophysical Studies Using DAS

   Presenter: Nate Lindsey, Fiber Sense Pty Ltd, United States

    Presentation Details   Paper

   Invited

   φ-OTDR/DAS enables dense, long-range (1 - 200 km), array recordings of strain fields with exceptional sensitivity (< 1×10−9 strain) wherever optical fiber exists. The measurement is conventionally based on interferometrically extracting dynamic phase information of the Rayleigh backscattered light from one end of a single-mode fiber. Recently, φ-OTDR/DAS has expanded into telecommunications networking, seismology and geophysics, water infrastructure monitoring, and civil engineering.Authors: Nate Lindsey, Fiber Sense Pty Ltd
