In this work, we investigate the sensing performance of Fiber Bragg Gratings (FBGs) engineered to operate near EPs through precise structural tuning. This review provides a comprehensive overview of FBG sensor technology. Abstract—Exceptional points (EPs), intrinsic to non-Hermitian systems, exhibit singular spectral responses with extreme sen-sitivity to external perturbations, offering new opportunities for precision sensing. These microscopic structures within optical fibers have become the bedrock of cutting-edge sensor. Fibre Bragg Grating (FBG) sensors are now a revolutionary technology in the optical sensing area, recognized for their high sensitivity, immunity to electromagnetic interference, and reliability of operation in demanding environments.
To tackle this problem, we utilize the fully convolutional time-domain audio separation network (Conv-TasNet) model to produce a distinct spectral signal, which is then demodulated using the dual-weight centroid approach to determine the spectral signal's center wavelength. Fibre Bragg gratings are one of the most popular sensors with a huge number of applications. Determining the wavelength shift is the most important issue in precise measurements of. A demodulation algorithm is vital for a fiber Bragg grating (FBG) sensing system. In this paper, a novel demodulation algorithm based on the variable-step-size method and cross-correlation algorithm is proposed to demodulate the wavelength of an FBG.

Fiber optic pressure sensors use light modulation to measure pressure, offering high sensitivity, EMI immunity, and wide-ranging applications. These sensors are gaining popularity. Fiber-optic sensing (FOS) technology has emerged as a cutting-edge research focus in the sensor field due to its miniaturized structure, high sensitivity, and remarkable electromagnetic interference immunity.
Fiber-optic sensors use the physical properties of light when transmitting it via fiber-optic cable with glass or plastic fibers to detect objects. Compared with conventional sensing technologies, FOS demonstrates superior capabilities in. A fiber-optic sensor is a sensor that uses optical fiber either as the sensing element ("intrinsic sensors"), or as a means of relaying signals from a remote sensor to the electronics that process the signals ("extrinsic sensors"). Fibers have many uses in remote sensing.
