Abstract

The Segmented Pupil Experiment for Exoplanet Detection (SPEED) optical test bed is now ready for operation. SPEED is dedicated to high-contrast imaging at short angular separations with segmented telescopes. Its optical design allows a wide range of applications and the immediate goal is to demonstrate a high-contrast dark hole close to the stellar vicinity. This will be achieved by a combination of optimal wavefront shaping architecture, small inner working angle coronagraphy, and efficient complex field sensor for fine cophasing and dark hole generation.
