Fiber-Optic Monitoring: Detecting Micrometer-Scale Cracks

Glasfaserkabel als Sensornetzwerk an einer Betonbrücke, schematische Darstellung

Fiber-optic monitoring can resolve calculated crack widths in the micrometer range, distributed over hundreds of meters of structure rather than at a handful of discrete points. Christoph Monsberger, co-founder of ACI Monitoring, explains in this interview how distributed fiber-optic sensing works, how it was deployed across the Brenner Base Tunnel, and why the technology is […]
