Fading-Induced Phase-Fluctuation Reduction and SNR Enhancement in ϕ-OTDR Using Video Block-Matching 3-D Collaborative Processing

Coherent fading and random background noise are two major factors that degrade phase stability and weak-vibration detection in distributed acoustic sensing (DAS) systems. Coherent fading induces local amplitude fading and phase-demodulation instability, whereas random background noise obscures vibration responses and l...

PSEW-VLM: An Interactive Distributed Fiber Optic Sensing Model for Threat Identification and Decision-Making in Oil and Gas Pipelines

Oil and gas pipelines are core infrastructure for energy transportation. They present critical challenges in safety monitoring and threat detection to ensure energy supply and public safety. Conventional AI-based recognition models for early warning in distributed fiber-optic sensing still exhibit significant limitatio...

Overcoming Label Scarcity in Distributed Acoustic Sensing via Masked Spectrogram Modeling

Distributed acoustic sensing (DAS) enables continuous monitoring of large-scale infrastructure, but the deployment of robust intelligent systems is severely hindered by the scarcity of expertly annotated data, cross-environmental domain shifts, and spatial biases caused by irregular physical fiber geometries. To addres...
