| Abstract: | This article focuses on the low current sensitivity of fiber current sensor,and demonstrates a novel fiber current sensor using the fiber ring resonator.The design combines the current sensor with the fiber ring resonator,and uses the pulse light to detect current.The optical signal can traverse the sensor head repeatedly so that the current sensitivity is enhanced efficiently.Compared with the traditional fiber current sensor,the new design has advantages including simple structure,easy fabrication and low cost. |
