Over the last three decades, the world of fiber optic sensing has undergone a remarkable transformation, propelling us from the pioneering days of distributed temperature sensing (DTS) in the 1990s to the cutting-edge inclusion of optical-based pressure gauges, seismic accelerometers, flowmeters, and an array of innovative point sensors in the 2000s. Fast forward to the 2010s, and the introduction of distributed acoustic sensing (DAS) has further revolutionised the optical sensing system, encompassing fibers, cables, sensors, deployment, processing, and interpretation technologies.
