Fiber optic sensing for civil infrastructure
This paper presents an overview of ISIS Canada's development and application of fiber optic sensing systems in a variety of civil infrastructure projects. Three types of fiber optic sensors have been utilized in ISIS projects-to-date: fiber Bragg gratings (FBGs), Fabry-Perot sensors, based on measuring displacement between two fibers; and a new sensor called a `long gauge (LG)', which employs a low coherence interferometry technique to measure deformations over gauge lengths ranging from 10 cm to 40 m. Details on the operation of the LG system are described below. Applications of the FBG and LG sensors are given for several ISIS projects that also involved the rehabilitation and strengthening of concrete structures using advanced composite materials.
