Over the past decade, a large body of work has demonstrated improved designs over the conventional 2×2 modulation scheme (based upon polarizer orientation angles of {0, 90, 45, 135}o) used in the manufacture of DoFP polarimeters. These designs show better usage of bandwidth and reduction of crosstalk across the various linear Stokes vector channels in the frequency domain. While much focus has been on the development of optimal modulation schemes for these devices, little attention has been given to the development of corresponding demosaicing strategies for these modulators. In this work, we adapt a recent demosaicing strategy based upon a conditional generative adversarial network (cGAN) developed for conventional 2×2 DoFP sensors to accommodate alternative modulation schemes. We collect full-resolution polarized intensity data at non-conventional polarizer angles using a division-of-time (DoT) visible imaging polarimeter that we use to simulate DoFP data from alternative modulators for training and testing purposes. We then assess performance across these alternative modulation strategies and compare results against the conventional modulation scheme.
