The dynamic characterization of a medieval bell tower, forced by its own bell is obtained by using a newly developed interferometric sensor. The displacement of the tower is remotely detected, without installation of contact sensors and the use of a cumbersome vibrodyne for structure excitation.

Abstract
The dynamic characterization of a medieval bell tower, forced by its own bell is obtained by using a newly developed interferometric sensor. The displacement of the tower is remotely detected, without installation of contact sensors and the use of a cumbersome vibrodyne for structure excitation. The measurement technique demonstrated in this paper allows heritage bell towers to be monitored in a simple and rapid way.
