Fiber optic sensing for structural health monitoring in harsh environments advancing degradation physics signal robustness and long term reliability prediction

Fiber optic sensing (FOS) technologies have emerged as transformative platforms for structural health monitoring (SHM) of critical infrastructure operating in harsh environments. Unlike conventional electrical sensors, fiber optic sensors offer intrinsic immunity to electromagnet...

Physics-Guided Windowed Symmetry Metrics for Improved Green’s Function Retrieval in Passive Distributed Acoustic Sensing Ambient Noise Interferometry

Distributed Acoustic Sensing (DAS) has revolutionized ambient noise interferometry, yet the reliability of retrieved empirical Green’s functions (EGFs) remains highly sensitive to non-diffuse noise fields and anthropogenic transients. In complex or noisy environments, global metr...
