Abstract
Future large aperture telescopes and high contrast imaging systems will often include segment gaps, structural obscurations, along with outer edges which produce diffraction effects that are disadvantageous to high contrast imaging (e.g., for exoplanet detection) or continuous wavefront control across the optical aperture. We present an optimization strategy for several pupil segment topologies for next-generation telescope concepts. Wave propagation results based on diffraction-limited point spread function analyses using Fraunhofer diffraction theory are presented using the Python-based POPPY simulation tool.

This research was made possible in part by the Gordon and Betty Moore Foundation program and the Technology Research Initiative Fund Optics/Imaging Program. The preliminary and benchmark PSF analysis was performed with the FRED Optical Analysis Software Package developed and maintained by Photon Engineering, LLC of Tucson, AZ. Also, this research made use of POPPY, an open-source optical propagation Python package originally developed for the James Webb Space Telescope project.Attached Files
