Interactive anomalies of pipelines represent important contributors to pipeline incidents, but
monitoring interactive anomalies is challenging. This paper presents an approach to monitor …

The integrity of gas pipelines is important for fuel delivery, but pipeline leaks frequently occur
for a variety of reasons. As a result, pipeline leak detection for gas pipelines is now an …

The development of advanced distributed optical fiber sensing systems that are capable of
performing accurate and spatially resolved multiparameter measurements is of great interest …

This paper is dedicated to the investigation of the metrological properties of phase-sensitive
reflectometric measurement systems, with a particular focus on addressing the non …

The structural health of fiber-optic communication networks has become increasingly
important due to their widespread deployment and reliance in interconnected cities. We …

For distributed fiber-optic sensors, slowly varying vibration signals down to 5 mHz are
difficult to measure due to low signal-to-noise ratios. We propose and demonstrate a forward …

This article presents a novel method for monitoring leakage in buried natural gas pipelines.
The method is based on phase-sensitive time-domain distributed reflection detection …

We propose a triangular chirp method in chirped-pulse phase optical time domain
reflectometry (CP Φ-OTDR) by utilizing both (up and down) chirp within the pulse without …

With the development of distributed fiber optic sensing, the recognition of different vibration
modes has become increasingly important. In this paper, a distributed external-heterodyne φ …

Submarine pipelines and cables are vital for transmitting physical and digital resources
across bodies of water, necessitating regular inspection to assess maintenance needs. The …
