Abstract

The SPEED test-bed is completed and operational at Lagrange Laboratory in Nice. The bench optical design allows a wide range of applications in high-contrast imaging: cophasing optics, coronagraphy, and wavefront shaping for large segmented on-axis telescopes. SPEED offers an ad hoc and representative lab environment for studying the effect of pupil fragmentation in a high-correction contrast regime to assess quasi-static speckle control and stability. The SPEED prime goal is to demonstrate high contrast at short angular separations with an unfriendly telescope aperture. After years of developments, from early design to first lights, we thoroughly present the SPEED facility by discussing the principal elements that have driven the design. The main characteristics and exploitation modes of this unique facility are presented.
