摘要

根据光在单模光纤中传播时的偏振态随外部应变变化的原理,我们提出了一种基于机器学习和偏振的光纤传感器系统,用于多点应变测量。为了解决前传感器对后传感器的影响,并最大限度地减少无关输入的干扰,我们采用了一种数据处理方法,为每个传感器构建一个单独的神经网络模型。这种方法将传感器反射光的偏振状态作为神经网络的输入,将传感器的旋转角度作为输出,训练设计的神经网络进行学习。训练后的神经网络产生的预测输出与实验数据高度一致,测试数据的平均预测准确率达到 99%。这些结果验证了我们的传感器系统和数据处理方法的有效性。

Development of optical fiber strain sensor system based on machine learning and polarization
Based on the principle that the polarization state of light propagating in a single-mode fiber changes with external strains, an optical fiber sensor system based on machine learning and polarization for multi-point strain measurement is proposed. To address the influence of the front sensor on the rear sensor and to minimize interference from unrelated inputs, we have employed a data processing method that constructs an individual neural network model for each sensor. This approach uses the polarization state of the reflected light of the sensors as the neural networks’ input and the sensors’ rotation angles as the output, training the designed neural networks for learning. The trained neural networks produce predicted outputs that demonstrate high consistency with the experimental data, achieving an average prediction accuracy of 99% on test data. These results validate the effectiveness of our sensor system and data processing method.
