Speckle Analysis Method for Distributed Detection of Temperature Gradients with ΦOTDR

A method to extend the operation of traditional single-frequency phase-sensitive optical time-domain reflectometry (ΦOTDR) to the monitoring of distributed temperature gradients along an optical fiber is proposed and experimentally validated. The measurement principle is derived from the perturbatio...
