摘要

光纤电流传感器的电流测量精度受传感光纤的机械振动、声扰动和温度变化等环境扰动的影响。本文提出了一种新的光纤偏振电流传感器(RFOC)局部振动对电流测量误差影响的数学模型及其振动补偿技术。利用沿传感光纤偏振变化的数值研究结果，找出了局部振动引起的电流测量误差。

Numerical analysis of localized vibration effects and its compensation technique on reciprocal fiber-optic polarimetric current sensor

Accuracy of current measurement in optical fiber current sensor is affected by the environmental perturbations such as mechanical vibrations, acoustic perturbations and temperature changes to the sensing fiber. This paper presents a novel mathematical model for localized vibration effects on current measurement error in reciprocal fiber-optic polarimetric current sensor (RFOC) and its vibration compensation technique. The results of numerical investigation of the variation of polarization along the sensing fiber are used to find the current measurement error due to localized vibration.
