17 October 2012Distributed monitoring of fiber Bragg gratings under local lateral loads using optical frequency domain reflectometry
We demonstrate distributed monitoring of long-length fiber Bragg gratings (FBGs) under lateral loads using optical
frequency domain reflectometry (OFDR). Local lateral loads are applied to a certain area of the long-length FBGs. We
observe splits of Bragg peaks due to the lateral loads in a distributed manner. We calculated the lateral loads based on the
amount of Bragg peak splits, which showed the good agreement with the applied loads.
