Project Description
Virginia Tech will develop a first-of-a-kind technology for remote fiber optic generation and detection of acoustic waves for structural health monitoring. The technology requires no electric power supply at the monitoring site and the detected acoustic signature as well as the additional returned optical signal allow extraction of information about multiple material conditions including temperature, strain, corrosion, and cracking.
Project Benefits
This project will develop an embedded, remotely controlled/monitored quasi-distributed sensing network for non-destructive evaluation of advanced fossil power systems. This fiber optic system will have unprecedented capability for structural health monitoring in advanced power systems, which will provide effective remote real-time assessment of critical material operating conditions for safe and reliable operation. The expected impact of this technology is lower-operating costs, higher availability and efficiency, and lower emissions.
