Optical Fiber Sensors vs. Conventional Electrical Strain Gauges for Infrastructure Monitoring Applications
Public infrastructure, including bridges, pipelines, tunnels, foundations, roadways, dams, etc., is subject to factors that can degrade it or lead to malfunctions. These structural problems can be the result of deterioration, improper construction methods, seismic activity, nearby construction work, etc. Although electrical strain gauges have long been used for monitoring structural changes, they sometimes lack the durability and integrity necessary to provide accurate, actionable information over extended periods. The applications in this white paper demonstrate how optical fiber sensors can offer a variety of economic and performance advantages.
