2013 GSDAA Finalist: Fiber-Optic Strain Gages Protect Restoration of Milan Cathedral

2013 Structural and Physical Test and Monitoring Finalist
Fiber-Optic Strain Gages Protect Restoration of Milan Cathedral

Author: Dr. Alfredo Cigada, Politecnico di Milano

Challenge: Creating a continuous structural monitoring system that delivers highly sensitive and stable strain measurements of a large structure in a challenging environment.

Solution: Developing an optical sensor system based on the NI PXIe-4844 optical sensor interrogator that consists of fiber Bragg grating (FBG) strain gages distributed on optical fiber, which is immune to lightning and other environmental effects.
