What is the working principle of fiber optic sensor

A fiber optic sensor operates on the principle of modulating light that travels through an optical fiber. It measures physical quantities by detecting changes in the intensity, spectrum, phase, or polarization of the light as it interacts with the environment. When light from a source, such as a laser, is transmitted through the fiber, any variations in the fiber's parameters—like temperature or pressure—affect the light signal, which is then detected and converted into an electronic signal for analysis . Additionally, specific applications, such as fiber optic current sensors, utilize the Faraday Effect, where a magnetic field alters the polarization of light in the fiber .
