Intensity Modulation Fiber Optic Sensing Report
Abstract- This paper presents a novel approach to physical displacement-based power grid measuring via an Intensity Modulated Fiber Optic Sensor {IMFOS). An IMFOS utilizes one fiber to transmit the intensity modulation light from its Electro-Optic controller to a fiber optic probe. Intensity-modulated fiber optic sensors (IM-FOSs) represent a cost-effective and structurally simple alternative to phase-based and wavelength-based optical sensors. Their operational principle enables the development of robust, scalable, and multiplexable systems suitable for a wide range of. This study introduces a cost-effective solution and sensor arrays for the multipoint liquid-level measuring sensor based on an intensity modulation technique. The sensor structure is based on the twisting of two fibers and creates cascading to achieve a multipoint detection.
