Abstract

The system construction and sensing principles of the optical fiber magneto-optic current sensor (OFMCS) based on the Faraday effect are presented. Meanwhile, the hardware and software of this kind of OFMCS which includes photo-electronic detection, signal processing, and automatic data acquisition and processing by computer are also described. The experimental results show that the measurement error of this kind of OFMCS caused by long- term stability is better than 0.5%.
