    Area of Science:

    • Optoelectronics and Photonics
    • Fiber Optic Sensing Technologies
    • Materials Science

    Background:

    • Distributed optical fiber sensing is crucial for structural health monitoring and environmental sensing.
    • Accurate and independent measurement of temperature and strain is challenging in existing fiber optic systems.
    • Current methods often suffer from cross-sensitivity or require complex setups.

    Purpose of the Study:

    • To propose and experimentally demonstrate a novel method for distinct temperature and strain evaluation using distributed optical fiber sensing.
    • To achieve independent distributed temperature and strain profiling along a polarization-maintaining fiber.
    • To compare the performance of the proposed method with existing Brillouin-based approaches.

    Main Methods:

    • Utilizing coherent Rayleigh scattering for sensing.
    • Combining phase-sensitive optical time-domain reflectometry (ϕOTDR) with ϕOTDR-based birefringence measurements.
    • Employing a polarization-maintaining fiber for distributed measurements.

    Main Results:

    • Independent distributed temperature and strain profiles were successfully obtained along a 100 m-long fiber.
    • The proposed system demonstrated measurement uncertainties of approximately 40 mK for temperature and 0.5 με for strain.
    • Theoretical analysis confirmed the superior performance and lower uncertainties compared to Brillouin sensing.

    Conclusions:

    • The developed coherent Rayleigh scattering-based method provides accurate and independent distributed temperature and strain measurements.
    • The ϕOTDR-based approach offers a simpler experimental layout and better performance than Brillouin sensing.
    • This technique holds significant potential for advanced fiber optic sensing applications requiring high precision.
