Multi-modal Distributed Fiber Optic Sensing (DFOS) is being developed to monitor strain, temperature and observing AE signals from damage and impact in such structures as submarines, surface ships and aircraft. Advantages of DFOS include:
- Small footprint
- Global inspection system
- No electromagnetic interference
- Unattended operation
- Could be used in harsh environments
- Large areas could be inspected rapidly
WINS’ prefabricated fiber optic sensors used for pipeline monitoring are shown below.
