Civil infrastructure monitoring using distributed interferometric measurements Distributed Acoustic Sensing webinar

The development of quantitative distributed acoustic sensing has paved the way for extremely sensitive dynamic displacement and strain measurements of civil infrastructure….In this webinar, two demonstrations of coupled DAS for civil infrastructure monitoring are presented. First, a model wind turbine is monitored for how its dynamic structural behavior changes when flange bolts loosen. Second, a hot-mix asphalt roadway is monitored for its dynamic strain behavior when events occur on the road surface….a first-of-its-kind use of ϕ-OTDR for structural health monitoring to demonstrate its capabilities.
