Paper Abstract

The experimental validation of a numerical technique for temperature/strain sensing, based on frequency domain fiber-optic Brillouin measurements, is presented. In this technique both measurements and the signal processing are performed in the frequency domain. The algorithm is based on a harmonic expansion of the unknown profile, whose coefficients are determined by means of a multidimensional minimization. Preliminary results prove the validity of the proposed technique.
