TL;DR: In 2014, the Science Definition Team (SDT) of the Wide Field Infrared Survey Telescope (WFIRST) mission presented a design reference mission (DRM) for an implementation of WFIRST using one of the 2.4m, Hubble-quality telescopes recently made available to NASA as discussed by the authors.
Journal ArticleDOI
Optimal pupil apodizations of arbitrary apertures for high-contrast imaging.
TL;DR: This work presents fully optimized two-dimensional pupil apodizations for which no specific geometric constraints are put on the pupil plane apodization, apart from the shape of the aperture itself, in the context of exoplanet direct detection and characterization.

TL;DR: In this article, the authors present a design reference mission for the WFIRST-2.4 DRM that employs one of the 2.4m, Hubble-quality mirror assemblies recently made available to NASA.
Journal ArticleDOI
Analyzing the designs of planet finding missions
TL;DR: All four mission concepts are capable of detecting on the order of five Earthlike planets within a 5 yr mission, even if the authors assume that only one out of every 10 stars has such a planet.
Journal ArticleDOI
Optimal Occulter Design for Finding Extrasolar Planets
TL;DR: In this article, the authors explore the tradeoff between separation and occulter diameter and present a method for designing the shape of the outer edge of an occulters that is as small as possible and gives a shadow that is deep enough and large enough for a 4m telescope to survey the habitable zones of many stars for Earth-like planets.
