Abstract:Starshades are a leading technology to enable the detection and spectroscopic characterization of Earthlike exoplanets. In this paper we report on optical experiments of sub-scale starshades that advance critical starlight suppression technologies in preparation for the next generation of space telescopes. These experiments were conducted at the Princeton starshade testbed, an 80 m long enclosure testing 1/1000 th scale starshades at a flight-like Fresnel number. We demonstrate 10 −10 contrast at the starshade… Show more
