Distributed optical fibre audible frequency sensor

Distributed optical fibre audible frequency sensor
Distributed optical fibre audible frequency sensor
A distributed optical fibre sensor is demonstrated which is capable of quantifying acoustic and dynamic strain disturbances along a 1km sensing fibre. A phase-OTDR technique is used to detect the dynamic perturbations using the phase-difference between the backscattered light from two separate sections of the sensing fibre. The demonstrated sensor detects multiple dynamic perturbations simultaneously within a frequency range of 200Hz to 5000Hz with a frequency resolution of 10Hz and a spatial resolution of 1m.

Abstract

A distributed optical fibre sensor is demonstrated which is capable of quantifying acoustic and dynamic strain disturbances along a 1km sensing fibre. A phase-OTDR technique is used to detect the dynamic perturbations using the phase-difference between the backscattered light from two separate sections of the sensing fibre. The demonstrated sensor detects multiple dynamic perturbations simultaneously within a frequency range of 200Hz to 5000Hz with a frequency resolution of 10Hz and a spatial resolution of 1m.
