Conventional sensors are incapable of long-term performance monitoring of infrastructure due to environmental and electromagnetic issues. However, fiber optic sensors are theoretically capable of permanent monitoring, while distributed fiber optic sensors can continuously monitor long distances from 20 km to 80 km. The group applies DFOS to various types of infrastructure such as tunnels, bridges, piles, retaining walls, and slopes
