    Area of Science:

    • Optoelectronics
    • Fiber Optic Sensing
    • Signal Processing

    Background:

    • Traditional sensing methods struggle with simultaneous acoustic and temperature measurements.
    • Temperature fluctuations can interfere with acoustic signal integrity.
    • Need for high-resolution, simultaneous multi-parameter sensing in various fields.

    Purpose of the Study:

    • To propose and demonstrate a novel sensing system for quasi-static temperature and dynamic acoustic signals.
    • To utilize ultra-weak Chirped Fiber Bragg Gratings (CFBG) for simultaneous sensing.
    • To enhance the signal-to-noise ratio (SNR) and accuracy of both acoustic and temperature measurements.

    Main Methods:

    • Employing an array of ultra-weak CFBGs for distributed sensing.
    • Utilizing cross-correlation for Distributed Temperature Sensing (DTS) by measuring spectral drift.
    • Gauging phase difference between adjacent CFBGs for Distributed Acoustic Sensing (DAS).
    • Applying a least square mean adaptive filter (AF) for signal enhancement.

    Main Results:

    • Achieved simultaneous detection of distributed acoustic and temperature signals.
    • Demonstrated acoustic signal SNR > 100 dB with a frequency response from 2 Hz to 1.25 kHz.
    • Obtained temperature measurements from 30°C to 100°C with an accuracy of ±0.8°C.
    • Achieved a spatial resolution (SR) of 5 m for the two-parameter sensing system.

    Conclusions:

    • The proposed CFBG-based system effectively performs simultaneous distributed acoustic and temperature sensing.
    • CFBG sensors isolate acoustic signals from temperature-induced drifts, preserving SNR.
    • The system offers high accuracy, resolution, and signal quality, suitable for demanding applications.
