Distributed Strain and Temperature Discrimination in Unaltered Polarization Maintaining Fiber
In this paper we present a technique that enables strain and temperature measurement and discrimination
using a single, polarization-maintaining (PM) fiber. The measurement is performed using instrumentation and fiber
that are standard products, readily available on the market.
A Rayleigh scatter-based distributed measurement technique is presented in which strain and temperature discrimination is achieved using standard polarization maintaining fiber as the sensor. High-sensitivity Optical Frequency Domain Reflectometry is used to measure the scatter.
