Distributed Fiber Optic Sensing System for Bridge Monitoring (1.5)

The problem the research team is trying to solve is how to monitor aging bridges. This is important because managing aging civil infrastructure is a major challenge facing the U.S and countries worldwide. Deterioration and premature failures of civil infrastructure have a critical impact on the U.S. economy. Fiber optic sensors are good candidates to monitor and inspect the status of bridges because they can provide fast and accurate measurements on strain and temperature. Asset owners are able to prioritize maintenance and repair of bridges based on the data provided by the fiber optic sensors. The objective of this project is to develop fiber optic sensing system using BOTDR (Brillouin Optical Time Domain Reflectometry) for monitoring of civil infrastructure systems such as highway bridges.
