Time shifting deviation method enhanced laser interferometry:ultrahigh precision localizing of traffic vibration using a urban fiber link
文献摘要：
Using a fiber network as a huge sensing system will enrich monitoring methods of public infrastructures and geological disasters.With the traditional cross-correlation method,a laser interferometer has been used to detect and localize the vibration event.However,the random error induced by the cross-correlation method limits the localization accuracy and makes it not suitable for ultrahigh precision localizing applications.We propose a novel time shifting deviation(TSDEV)method,which has advantages over the cross-correlation method in practicabil-ity and localization accuracy.Three experiments are carried out to demonstrate the novelty of the TSDEV method.In a lab test,vibration localization accuracy of～2.5 m is realized.In field tests,TSDEV method en-hanced interferometry is applied to monitor the urban fiber link.Traffic vibration events on the campus road and Beijing ring road have been precisely localized and analyzed,respectively.The proposed technique will extend the function of the existing urban fiber network,and better serve the future smart city.
