Abstract :
Various applications of fiber optic current sensor are explored now. In this paper a new full-optical current sensor is designed. The fiber-optic current sensor is based on the Faraday rotation effect, and moreover, in this paper the mechanism of Faraday rotation effect of cylinder fiber model is explained. In the present research experimental platform has been set up. And then the Comsol software has been used to simulate the system´ transmission field, which could be achieved by calculating the transmittance of light propagating through POF. Finally the results obtained respectively by traditional structure and new structure are compared. The results may be helpful for the further research on the fiber optic current sensor.
