Home / All-fiber current interaction sensor
All-fiber optic current sensors (AFCSs) are mainly based on the Faraday effects in the coil of an optical fiber around a current conductor and have attracted significant interest in recent years owing to their immunity to compact design, fast response time, electromagnetic. We have experimentally developed a hybrid-structure multi-channel all-fiber current sensor with ordinary silica fiber using fiber loop architecture. According to the rationale of time division multiplexing, the sensor combines parallel and serial structures. The current-induced rotation angle is converted into a minute change in transmittance of the fiber loop, which.
