Abstract

Vector curvature fiber sensors have significant applications in many fields. Traditional fiber sensors rely on single peak demodulation, which often leads to inaccurate demodulation results. In this letter, a high-precision vector bending fiber sensor named Remodulate long-period fiber grating(Remodulate LPFG) is designed. We use the Residual multilayer perceptron model, which fully utilizes the information of multiple modes in the full spectrum to predict vector curvature. The results of the experiment show that the prediction accuracy is 99.93% with a mean absolute error (MAE) of 1.8° for bending direction measurement and 98.92% with an MAE of

$0.04~m^{-1}$

for the curvature measurement. Our experiments demonstrate that our model has high precision prediction. The high precision prediction and compacting structure consume Remodulate LPFG can unleash enormous value in engineering applications.

基于可调LPFG的机器学习辅助高精度矢量弯曲传感器

矢量曲率光纤传感器在许多领域有着重要的应用。传统的光纤传感器依靠单峰解调，这往往导致解调结果不准确。本文设计了一种高精度矢量弯曲光纤传感器——重调长周期光纤光栅（remomodulation LPFG）。我们使用残差多层感知器模型，该模型充分利用了全谱中多个模式的信息来预测向量曲率。实验结果表明，预测精度为99.93%，弯曲方向测量的平均绝对误差（MAE）为1.8°；曲率测量的平均绝对误差（MAE）为98.92%，误差为0.04~m^{-1}$。实验结果表明，该模型具有较高的预测精度。可调LPFG具有高精度的预测和压实结构，在工程应用中具有巨大的价值。
