Author Affiliations +
Polarization plays a significant role in nulling interferometry and should be considered early in the instrument design process. In this paper, I demonstrate that mirror trains with near-normal incidence angles increase the leakage into the central null more than other mirror trains for a given amount of misalignment perpendicular to the incidence plane. Also, throughput and polarization non-uniformity across a wave front will significantly increase the leakage. To simplify top-level modeling of this effect, I derive a "throughput/polarization" version of the Strehl ratio.
