Confocal Fluorescence Microscopy01:16

Confocal Fluorescence Microscopy

Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...

    Area of Science:

    • Fiber optic sensing
    • Distributed sensing systems
    • Photonics and optical technologies

    Background:

    • Distributed multi-parameter fiber sensing requires high signal-to-noise ratio (SNR) for accurate measurements.
    • Traditional methods face limitations in SNR, especially over long distances.
    • Phase-sensitive optical time-domain reflectometry (φ-OTDR) is a key technique for distributed sensing.

    Purpose of the Study:

    • To propose and demonstrate an enhanced hybrid distributed multi-parameter fiber sensing system.
    • To improve the SNR of Rayleigh backscattering using distributed Brillouin amplification.
    • To achieve simultaneous distributed acoustic and temperature sensing.

    Main Methods:

    • Utilizing a continuous optical chirp chain (OCC) as a Brillouin pump for uniform probe pulse amplification.
    • Employing a Brillouin loss scheme to extract temperature information from OCC.
    • Implementing a 60 ns segment duration and 250 MHz sweeping range for OCC.
    • Conducting experiments over 50 km of single-mode fiber.

    Main Results:

    • Achieved a 10 dB enhancement in the SNR of φ-OTDR at the fiber end.
    • Demonstrated distributed acoustic sensing with a strain sensitivity of 64 pε/Hz1/2.
    • Achieved distributed temperature sensing with a precision of 0.2 ℃.
    • Maintained a spatial resolution of 6 m over the 50 km fiber.

    Conclusions:

    • The proposed enhanced hybrid distributed sensing system significantly improves SNR.
    • The system effectively enables simultaneous distributed acoustic and temperature sensing.
    • This approach offers a robust solution for long-range, multi-parameter fiber optic sensing.
