Abstract

The influences of imperfect polarization induced effects are investigated in this paper for a novel optical voltage sensor (OVS), which consists of quasi-reciprocal reflective optical interferometer and digital closed-loop detection scheme. The numerical models are established to describe the relationship between the characteristic parameters of imperfect polarization and the performances of the OVS, which is also simulated to investigate quantitatively. The numerical models and the simulated results are experimentally verified with typical imperfect polarization induced errors. Accordingly, the primary characteristic parameters of imperfect polarization are illuminated. What's more, the conclusions of this paper can provide useful references for the design and performance improvement of the novel Pockels effect based OVS.
