Phase-Induced Amplitude Apodization on centrally obscured pupils : design and first laboratory demonstration for the Subaru Telescope pupil

Abstract

High contrast coronagraphic imaging is challenging for telescopes with central obstructions and thick spider vanes, such as the Subaru Telescope. We present in this paper the first laboratory demonstration of a high efficiency PIAA-type coronagraph on such a pupil, using coronagraphic optics which will be part of the Subaru Coronagraphic Extreme-AO (SCExAO… (More)
