Paper Abstract

Long range simultaneous distributed strain and temperature sensors have many applications for measurements in the power and oil industries and also for structural monitoring. We present an efficient technique to measure both the intensity and frequency shift at every point along the sensitive fiber with a low loss filtering device utilizing two in-fiber Mach-Zehnder interferometers. From these two measurements, it is possible to compute accurately the strain and temperature profile.
