To address the challenge of efficiently identifying and providing early warnings for typical structural damages in small and medium-sized bridges during long-term service, this paper proposes an intelligent monitoring and recognition method based on ultra-weak fiber Bragg grating . In the vast realm of optical fiber sensing, where precision and innovation converge, Fiber Bragg Gratings (FBGs) stand as luminaries, casting their influence across myriad applications. These microscopic structures within optical fibers have become the bedrock of cutting-edge sensor. 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.

Serbian Fiber Bragg Grating Upgrade Version
A fiber Bragg grating (FBG) is a type of constructed in a short segment of that reflects particular of light and transmits all others. This is achieved by creating a periodic variation in the of the fiber core, which generates a wavelength-specific. Hence a fiber Bragg grating can be used as an inline to block certain wavelengths, can be use.

Items made by fiber optic sensors
Optical fibers can be made into interferometric sensors such as fiber-optic gyroscopes, which are used in the Boeing 767 and in some car models (for navigation purposes). They are also used to make hydrogen sensors. Their high sensitivity, immunity to electromagnetic. Fiber optic current sensors are revolutionizing the way electrical currents are measured, providing high sensitivity, immunity to electromagnetic interference (EMI), and the ability to function in harsh environments. These sensors are capable of measuring a wide range of physical and chemical parameters such as temperature, pressure, vibration, displacement.

What are the specific applications of LED fiber optic communication
In optical fiber communication systems, LEDs serve as optical sources to convert electrical signals into light pulses. Unlike old-fashioned light bulbs that get hot and burn out, LEDs produce light very coolly and efficiently. The light from the transmitter is coupled into the fiber with a connector and is transmitted through the fiber optic cable plant.

Examples of Fiber Optics in Sensors
Optical fibers can be used as sensors to measure, , and other quantities by modifying a fiber so that the quantity to be measured modulates the,,, or transit time of light in the fiber. Sensors that vary the intensity of light are the simplest, since only a simple source and detector are required. A particularly useful feature of intrinsic fiber-optic sensors is that they can, if required, provide distributed sensing over very large distances.
