Abstract

We conducted a strain characterization experiment to detect concrete beam cracks using distributed Brillouin sensor system. An accurate Brillouin multiple-peak fitting method is used to enhance the spatial and strain resolution. This allows us to exactly extract the distributed strain section that is smaller than the spatial resolution of the Brillouin sensor system.
