Abstract :
In this paper, a unique software program is reported, which automatically decodes the Faraday rotation signal into a time-dependent current representation. System parameters such as the Faraday fiber´s Verdet constant and the number of loops in the sensor are the only user-interface inputs. The central aspect of the algorithm utilizes a short-time Fourier transform, which reveals much of the Faraday rotation measurement´s implicit information necessary for unfolding the dynamic current measurement.
