title = "Laboratory performance of the shaped pupil coronagraphic architecture for the WFIRST/AFTA coronagraph",
abstract = "One of the two primary architectures being tested for the WFIRST-AFTA coronagraph instrument is the shaped pupil coronagraph, which uses a binary aperture in a pupil plane to create localized regions of high contrast in a subsequent focal plane. The aperture shapes are determined by optimization, and can be designed to work in the presence of secondary obscurations and spiders-an important consideration for coronagraphy with WFIRST-AFTA. We present the current performance of the shaped pupil testbed, including the results of AFTA Milestone 2, in which as \& 6 × 10-9 contrast was achieved in three independent runs starting from a neutral setting.",
