Hierarchical Error Suppression for High-Precision Displacement Reconstruction in OFDR-Based Distributed Inclinometers

Distributed optical fiber sensing (DOFS) based on optical frequency domain reflectometry (OFDR) provides millimeter-scale spatial resolution for distributed deformation monitoring in geotechnical infrastructure. However, the enhanced sensitivity of OFDR also makes measured strain fields vulnerable to localized nonphysi...

An Intelligent Bearing Fault Diagnosis Model with Physics-Information Fusion: Design and Interpretability Mechanism Research

To address the issue of limited interpretability in current deep learning-based bearing fault diagnosis methods, this study proposes a convolutional neural network model incorporating spectral physical constraints. The model integrates data-driven learning with physical constraints by embedding the spectral features of...
