Abstract

We present a numerical study of the diffraction effects and controllability of telescope assembly polarization aberrations on apodized pupil Lyot coronagraph (APLC) and vector vortex coronagraph (VVC) designs for the LUVOIR-A and LUVOIR-B mission concepts. We also examine interactions between polarization aberrations and vector vortex masks, which induce a geometrical helical phase to achieve deep nulling of incident starlight.
