报告人简介：  

Dr. Linqing Luo is the postdoc in University of California, Berkeley and Lawrence Berkeley National Laboratory. He received a Ph.D from the University of Cambridge, UK. Before that, he studied in University of Liverpool and University of Cambridge for his Bachelor and MRes Degrees. His research focuses on the fiber optic sensing and its application in smart infrastructure.

报告简介：

The future looks “smart” for infrastructure after the infrastructures are armed with several advanced sensors. Distributed Fiber Optic Sensing (DFOS) is one of the promising tools for structure health monitoring. It can measure physical quantities (such as temperature, strain, and vibration) along the optic fiber continuously (say 5 cm interval) along its length for long distance (say 50 km). The main advantage is its high sensitivity over large distances and the ability to interface with a wide range of measurands in a distributed manner. The systems provide thousands of “strain gauges”, “thermo-couples”, or “accelerometers” along a single fiber optic cable connected to or embedded in structures, which can then serve as a civil infrastructure nerve system. DFOS can provide a highly effective monitoring system for both short and long term to realize our concept of “smart infrastructure”. In this talk, we will discuss the basics of fiber optic sensing and several cases (including tunnels, piles, pipelines, foundation and pavement) in structure health monitoring for improving the safety and resilience of the infrastructure.
