This paper presents a comprehensive review of AI-enhanced OFS technologies, encompassing both localized sensors such as fiber Bragg gratings (FBG), Fabry–Perot (FP) interferometers, and Mach–Zehnder interferometers (MZI), and distributed sensing systems based on Rayleigh . If 5G is the neural conduction of the digital age and AI the super brain, fiber sensing serves as the quietly growing peripheral nerves. In 2023, a group from California Institute of Technology, collaborating with Google, achieved the world's first commercial submarine cable-based second-level. The Fiber Optic Sensing Association (FOSA) is dedicated to accelerating the use of distributed and quasi-distributed optical fiber sensing technologies. Fiber optic sensing works by measuring changes in the “backscattering” of light occurring in an optical fiber when the fiber encounters vibration. Over the last three decades, fiber optic sensors (FOS) have gained a lot of attention for their wide range of monitoring applications across many industries, including aerospace, defense, security, civil engineering, and energy. FOS technologies hold great promise to form the backbone for. The integration of artificial intelligence (AI) with optical fiber sensing (OFS) is transforming the capabilities of modern sensing systems, enabling smarter, more adaptive, and higher-performance solutions across diverse applications. This paper presents a comprehensive review of AI-enhanced OFS. Radiation absorption excites an orbital electron to a higher energy level. Heating the material enables the trapped states to interact with phonons and decay into lower-energy. In cooperation with our spin-off company Fionec GmbH, we offer a comprehensive overall concept consisting of probes, evaluation unit and measuring device. In addition to sensors for use in production measurement technology, Fraunhofer IPT develops and manufactures temperature and spectroscopy.
