Φ-OTDR (Phase-Sensitive Optical Time-Domain Reflectometry) technology is revolutionizing infrastructure monitoring by leveraging fiber optic cables to detect vibrations and acoustic signals in real-time. This cutting-edge technology enhances safety in critical infrastructures such as pipelines, bridges, tunnels, and urban utilities. With advanced signal processing methods, including Short-Time Fourier Transform (STFT) and machine learning, Φ-OTDR systems can detect and classify vibrations with exceptional accuracy. Real-world applications in border surveillance, oil and gas pipeline monitoring, urban utility systems, and aerial cable monitoring demonstrate the system's versatility and effectiveness in complex environments. As the technology evolves, the integration of artificial intelligence will further improve the system’s adaptability, ensuring safer and more efficient infrastructure management.
