Abstract

Acoustic field could be quite useful in structure health monitoring (SHM). Here we present an enhanced distributed acoustic sensing (DAS) system by implanting microstructures into the sensing fibre. Taking advantage of the interactions between nearby microstructures, the acoustic field could be reconstructed with high fidelity and signal-to-noise ratio (SNR) even at the rear end of 42.2km long sensing fibre. The experimental results have shown that the proposed sensing system has a linear intensity response of R2 = 0.9988, while its frequency response band ranges from 8Hz to 1 kHz. Purely distributed sensing along the optical fibre has been obtained even with discretely implanted microstructures for the proposed system, which offers a dependable option for acoustic field monitoring.
