Title: Dynamic sensitivity distributed acoustic sensing
Inventor: GREGOR CEDILNIK
IPC: G01L1/24
Filed: 2017-03-13
Abstract: A method of determining a strain change in an optical fiber comprises injecting pulsed radiation from a source (103) into an optical fiber (101). The light is backscattered (by for example Rayleigh scattering) and the return signal (109) is interfered with a local oscillator reference signal (111). Multiple intensities corresponding to the multiple locations are received by detector (115) and stored in processor (117). Temporal phase changes corresponding to each location are determined and stored. A variable first aggregation range (window size) is set to an initial value, and an aggregated value relating to the phase change determined. This is first carried out for locations behind a target position, and then again for locations in front of a target position. The difference between the aggregated values is determined and compared to a criterion (such as a noise threshold). The aggregation ranges are varied until the criterion is satisfied. The aggregation range widths and locations may be different, but they may share a either a common start or end point. The presence of fading may be identified and used to aid aggregation range selection. An arrangement for performing the method is also disclosed.
