METHOD AND SYSTEM FOR ENHANCING THE SPATIAL RESOLUTION OF A FIBER OPTICAL DISTRIBUTED ACOUSTIC SENSING ASSEMBLY

The spatial resolution of a fiber optical Distributed Acoustic Sensing (DAS) assembly is enhanced by: - arranging an optical DAS fiber (1) with a series of contiguous channels (C1-C14) that are sensitive to vibration in a U-shaped loop (Ul) such that substantially parallel fiber sections ( IA, IB) c...
