Design an optical fiber current sensor

Design of a current sensor based on optical fibers This paper present the design of a current sensor based on Faraday Effect using optical fibers devices and a polarizing beam splitter (PBS). Two different schematics are to be taken into account, for high currents. Accurate measurement of electrical current in devices is a fundamental technology that is essential for controlling and monitoring the systems and equipment that many industries and our daily lives depend upon. Typically, current transformers have been used to measure electric current. The superposition principle of composite OAM beam is deduced, and the current sensing process is derived by Jones matrix.
