Verdet constant dispersion measurement using polarization-stepping techniques.
We present a novel method for measuring the Verdet constant dispersion. The proposed method involves spectral polarimetric measurements using three (or more) polarization steps. The procedure has formal similarity with the phase-shifting interferometry (PSI). Thus the Verdet constant in the desired spectral range can be retrieved using well-known PSI algorithms. Validation experiments are presented.
