Title: Segmented Coronagraph Design and Analysis (SCDA) Study
Reaching high contrast ratios at close angular proximity to a star is an extremely challenging undertaking for a coronagraph with a filled-aperture telescope and is even more challenging with segmented, partially obscured apertures proposed for a large space-borne observatory. The primary goal of the ExEP-funded SCDA study is to identify coronagraph designs that maximize exo-Earth detectability with a variety of segmented apertures including hexagonal-segment and pie-wedge segment architectures. Both on-axis and off-axis designs are considered. The SCDA study is funding the design of pupil-plane, image-plane, and hybrid coronagraph designs. In this presentation, we discuss the progress in coronagraph designs and science yield performance since the study began in January 2016
The intention of these web seminars is to provide a forum for sharing key technology advances and results that enable or enhance the direct imaging and characterization of exoplanets. Topics may include recent coronagraph and starshade demonstration results, advances in detector technology, deformable mirrors, LOWFS/C, telescope stability, polarization, RV, starshade tutorials, etc. Our target audience is the engineers and scientists working on the WFIRST project and the HabEx and LUVOIR study concepts, but all are welcome to attend.
The series will be recorded and publically archived on this page so that they can be viewed at later dates.
