Paper Abstract

The measurement of thermal expansion of a 5 meter length concrete beam by embedded fiber-optic interferometric sensors is reported. The measurement has been done by a scheme which permits to solve the fiber strain-temperature cross-sensitivity by a contemporary reading of both the optical path length and the dispersion parameter of the fiber. The reported experimental data confirm the suitability of the technique for simultaneous detection of absolution strain and temperature.
