Detecting the direction of acoustic signals with a fiber optical distributed acoustic sensing (DAS) assembly
Abstract:
A directionally sensitive Distributed Acoustic Sensing (DAS) fiber optical assembly comprises adjacent lengths of optical fiber (A,B) with different directional acoustic sensitivities, which are used to detect the direction (a) of acoustic signals relative to the lengths of optical fiber (A, B).
Abstract(Chinese):
