Fraunhofer IPT develops fiber-optic sensors for challenging measurement tasks such as measuring the smallest of boreholes. Using fiber-integrated beam steering and shaping, individual sensors up to a diameter of 80 microns can be manufactured. In cooperation with our spin-off company Fionec GmbH. 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. Proximion designs and manufactures customized state-of-the-art fiber optic sensor systems for the measurement of temperature, strain, and other physical parameters. These systems harness the unique properties of light to provide accurate and reliable data across a spectrum of applications. They use optical fibers to transmit light signals that interact with. fionec's fiber-optic technology is predestined for measuring tasks that are difficult to accomplish using conventional measuring apparatus: The diminutive size of our probes, their contactless interferometric measurement principle and the flexible design of the sensor system make it possible to.
