Abstract

This article presents a novel phase-sensitive optical time domain reflectometry (Φ-OTDR) with a spatial resolution of 2-m on a 90-m fiber assisted by image-matching and dual-frequency. The temporal resolution was improved fourfold compared to the conventional Φ-OTDR based on the cross-covariance algorithm. Using the same temporal window, the measurement error was decreased from 21.4% to 1.2% in the distributed experiment, showing a considerable improvement in the measurement precision.
