| 摘 要： | 利用光纤抗电磁干扰、绝缘性好、体积小等特性，提出一种新型的光纤电流传感器。经比较，选择超磁致伸缩棒（Tb0.3Dy0.7Fe1.95）作为核心材料，对光纤F-P传感器实现电流测量的理论进行了研究分析，在解调方式上采用了相位解调法，建立了光纤F-P腔的数学模型，推导出电流检测理论公式，并进行了相关实验。

| Abstract: | Based on characteristics of anti-electromagnetic interference, good insulation and small volume of optical fiber,a new type of fiber-optic current sensor is given. Tb_(0.3) Dy_(0.7) Fe_(1.95) is used as core material. Current measurement theory is analyzed and phase demodulation method is adopted. The mathematical model of the F-P gap is built up and a current measurement equation is given. Some experiments are done. |
