    Area of Science:

    • Photonics and Optical Sensing
    • Biomedical Engineering
    • Acoustic Detection Systems

    Background:

    • Traditional ultrasound detection systems face limitations in multiplexing capacity and data acquisition speed.
    • Inconsistent operating wavelengths in fiber optic sensor arrays hinder efficient parallel detection.
    • Developing sensitive and high-resolution ultrasound detection is crucial for real-time imaging.

    Purpose of the Study:

    • To propose and demonstrate a multi-channel parallel ultrasound detection system using a photothermal tunable fiber optic sensor array.
    • To address the challenge of inconsistent operating wavelengths in sensor arrays through photothermal tuning.
    • To achieve high multiplexing capacity and low noise equivalent pressure for enhanced ultrasound detection.

    Main Methods:

    • Fabrication of a photothermal tunable fiber optic sensor array.
    • Utilizing a 980-nm heating laser for photothermal tuning of sensor resonant wavelengths.
    • Employing a fixed wavelength laser with an ultra-narrow linewidth for sensor interrogation.
    • Building and testing a four-channel prototype for parallel detection capability assessment.

    Main Results:

    • Achieved a resonant wavelength tuning range greater than 15 nm via photothermal effect.
    • Demonstrated theoretical multiplexing capacity up to 53 channels, significantly reducing data acquisition time.
    • Obtained a noise equivalent pressure (NEP) of 0.12 kPa, 5.5 times lower than commercial hydrophones.
    • Confirmed negligible signal-to-noise ratio (SNR) deterioration and low crosstalk in parallel detection.

    Conclusions:

    • The photothermal tunable fiber optic sensor array effectively solves wavelength inconsistency issues for high-capacity multiplexing.
    • The developed multi-channel system offers superior sensitivity and parallel detection capabilities with minimal crosstalk.
    • This parallel detection technique provides a promising pathway for real-time photoacoustic and ultrasound imaging.
