About

Wing Ko is a leading researcher in the field of distributed fiber optic sensing, with a particular focus on shape measurement and structural health monitoring. Their work centers on the development of multicore optical fibers and advanced interrogation techniques to probe micron-scale mechanical deformations with unprecedented precision. Ko’s major contributions include pioneering methods for continuous, distributed measurement of small length scale contortions along arbitrary paths, as demonstrated in their highly cited 2019 paper on twisted multicore optical fibers (20 citations). This work addresses a critical challenge in engineering and technology: the need to monitor structural integrity in real time. Building on this foundation, Ko’s 2020 study on measuring the shape of microbends (16 citations) introduced a novel approach using fibers with multiple waveguiding cores inscribed with weak continuous Bragg gratings. By analyzing distributed Bragg-reflectivity data, Ko enabled the precise characterization of small deformations along the fiber length. These achievements have significant implications for robotics, aerospace, and civil infrastructure, positioning Ko as a key innovator in the advancement of distributed optical sensing technologies.
