Harnessing the Power of Light: The Journey of Distributed Fiber Optic Sensors
Dr Huan Wu, The Hong Kong Polytechnic University
Abstract: Optical fiber, one of the top innovations in twentieth century, is a ubiquitous technology that powers a vast global network, providing high-speed, low latency Internet connectivity. Though widely known for its communication capabilities, optical fiber has another important application in the form of optical fiber sensors (OFSs). Traditional point sensors, which measure a single point or a small area, often fail to provide comprehensive data over large areas. To address this limitation, the concept of distributed fiber optic sensors (DFOSs) was introduced. DFOSs facilitate continuous, real-time monitoring of physical parameters along the entire length of the fiber, achieving a constant flow of data over expansive areas. This unique attribute makes DFOSs ideal for the surveillance of large structures such as pipelines, bridges, and dams, where abnormal or damages may span a significant distance. This talk will present the basic principles of DFOSs and explore some of their applications in industry.
Speaker’s Bio: Dr. Huan Wu received a B. Eng. Degree from Nanjing University of Aeronautics and Astronautics in 2013, followed by a Ph.D. degree from the Chinese University of Hong Kong (CUHK) in 2018. Serving as a postdoctoral fellow in the Department of Electronic and Information Engineering (EIE) at HK PolyU from 2018 to 2020 and later in the Department of Land Surveying and Geoinformatics (LSGI) at HK PolyU from 2020 to 2022, she currently is Research Assistant Professor in the Department of Electrical and Electronics Engineering (EEE). Her research interests include distributed fiber optic sensors and their applications. Dr. Wu has published over 20 papers on IEEE Communications Magazine, IEEE Transactions on Instrumentation and Measurement (TIE), IEEE Journal of Lightwave Technology (JLT), Optics Express (OE) etc. She also serves as a technical consultant for Water Supplies Department (WSD), The Hong Kong SAR Government.
