Temperature-strain discrimination in distributed optical fiber sensing using phase-sensitive optical time-domain reflectometry.
A method based on coherent Rayleigh scattering distinctly evaluating temperature and strain is proposed and experimentally demonstrated for distributed optical fiber sensing. Combining conventional phase-sensitive optical time-domain domain reflectometry (ϕOTDR) and ϕOTDR-based birefringence measurements, independent distributed temperature and strain profiles are obtained along a polarization-...
متن کاملDistributed Fiber Optical Sensing of Oxygen with Optical Time Domain Reflectometry
In many biological and environmental applications spatially resolved sensing of molecular oxygen is desirable. A powerful tool for distributed measurements is optical time domain reflectometry (OTDR) which is often used in the field of telecommunications. We combine this technique with a novel optical oxygen sensor dye, triangular-[4] phenylene (TP), immobilized in a polymer matrix. The TP lumi...

متن کاملOptimal detection bandwidth for phase-sensitive optical time-domain reflectometry
The spectrum of the temporal traces obtained from a phase-sensitive optical time-domain reflectometer is theoretically and experimentally analysed, demonstrating its dependence on the incident optical pulse shape. Numerical simulations and theoretical results are validated experimentally, showing a good matching for rectangular optical pulses. The influence of the photodetector bandwidth on the...
متن کاملDistributed Rayleigh scatter dynamic strain sensing above the scan rate with optical frequency domain reflectometry
Luna recently demonstrated a novel optical phase-based algorithm for removing the adverse effects of fiber motion at frequencies far above the scan rate on high-resolution measurements of Rayleigh scatter using Optical Frequency Domain Reflectometry (OFDR) for static strain and temperature measurements. By comparing dynamic OFDR Rayleigh scatter measurements to a static reference, it is possibl...
