| 摘 要： | 光纤电流传感器是把光纤缠绕在导线周围,光纤既是信息的传输元件又是信息的敏感元件,因此这种传感器的地面设备以外的部份就只是整根的光纤,这不但解决了绝缘问题,且具有抗电磁干扰、灵敏度高、测量动态范围大的优点,具有广泛的应用前景.二、基本关系式因光纤材料的Faraday效应,在长直导线上绕有N圈光纤时,其偏振光的旋转角度θ为:θ=VNI(1)式中V是Verdet常数.图1为实验系统简图.从波长为632.8nm的He-Ne激光器发出的激光束经

Experimental system of optical fiber sensor for current measurement and its performances |
| |
| Abstract: | An optical fiber sensor for current measurement has been constructed by using magneto-optical effect. In this paper the main problems have been discussed, such as selection and treatment of fiber, the structure of sensing head and the method of forming fiber coil, the design of detecting and processing system, the adjustment of the optical system etc. The measurement results of the experimental system are given as well. |
