Not just the Internet: Foresight uses optical fiber to detect structural damage after earthquakes

This experimental setup based on coherence scan interferometry was developed with INRIM. The fiber sensing system integrates sensitive monitoring of environmental and structural signals with micrometer resolution to integrate photonic and optoelectronic components that match optical fibers. Credit: inrim A new method based on optical interferometry is to monitor the structural damage of earthquake-hit buildings in real time, and is…
