On the Broadband Instrument Response of Fiber‐Optic DAS Arrays
Journal of Geophysical Research - Solid Earth, 2019Distributed Acoustic Sensing (DAS) is a novel tool in array seismology that measures the phase of backscattered laser pulses traveling in a fiber‐optic cable, and relates this measurement to the axial strain induced on the cable by a propagating seismic ...
