Paper Abstract
Recent efforts combining the optimization techniques of apodized pupil Lyot coronagraphs (APLC) and shaped
pupils have demonstrated the viability of a binary-transmission mask architecture for extremely high contrast
(10-10) exoplanet imaging. We are now building on those innovations to carry out a survey of Lyot coronagraph
performance for large, segmented telescope apertures. These apertures are of the same kind under considera-
tion for NASA's Large UV/Optical/IR (LUVOIR) observatory concept. To map the multi-dimensional design
parameter space, we have developed a software toolkit to manage large sets of mask optimization programs and
execute them on a computing cluster. Here we summarize a preliminary survey of 500 APLC solutions for 4
reference hexagonal telescope apertures. Several promising designs produce annular, 10-10 contrast dark zones
down to inner working angle 4λ0=D over a 15% bandpass, while delivering a half-max PSF core throughput
of 18%. We also report our progress on devising solutions to the challenges of Lyot stop alignment/fabrication
tolerance that arise in this contrast regime.
