Paper Abstract

This work presents the first example of structure mode shapes recovering by means of an embedded quasi-distributed fiber-optic sensor. The developed feed-forward quasi-distributed polarimetric sensor allows a distributed recovery of the structure strain while maintaining low- invasivity, high-sensitivity, and high spatial resolution. The first three modes of a CRFP cantilever have been recovered both in frequency and in modal shape by means of the 8- segment sensor. The excellent agreement between the theoretical datum and the experimental results confirms the suitability of the presented architecture in developing advanced sensing systems for structure application.
