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.
