SagnacAssisted Enhanced OTDR for Distributed Acoustic Sensing: A Standardized Benchmark and Engineering Evaluation Framework
arXiv:2606.05754v1 Announce Type: cross Abstract: Phase-sensitive optical time-domain reflectometry ($\phi$-OTDR) is widely used in large-scale distributed acoustic sensing (DAS) because it provides distributed spatiotemporal monitoring over long sensing distances. Its field performance can still deteriorate because of polarization-induced fading (PIF), local signal degradation, and strong environmental interference. This study develops a Sagnac-assisted enhanced $\phi$-OTDR sensing architecture and a standardized benchmark framework for engineering-oriented DAS event recognition. The Sagnac i
The continuous demand for more robust and reliable sensing technologies in diverse environments is driving innovation in optical fiber applications.
Improved distributed acoustic sensing (DAS) can enhance infrastructure monitoring, resource exploration, and potentially defense applications over vast distances.
This research offers a method to mitigate critical limitations in $\phi$-OTDR systems, leading to more dependable and accurate distributed acoustic sensing.

DAS systems will become more reliable and capable of deployment in harsher or more complex environments.
The increased fidelity of acoustic data could enable new forms of predictive maintenance or environmental monitoring.
Broader adoption of enhanced DAS technology might influence geopolitical strategies by providing superior long-range surveillance capabilities.
