Paper Abstract

In this work we describe an optical sensor to determine the stress applied at a concrete structure. The optical sensor is a monomode fiber optic, that is embedded in the concrete. The principle of these sensors is based on photoelastic effect, that produces a birefringence in the optical fiber and induces a rotation on the polarization angle of the guided polarized light. The photoelastic effect is produced due to a controlled applied charge in the center of the concrete structure. The shift of polarization is analyzed by a polaroid analyzer.
