CORONOGRAPHIC INSTRUMENTATION AT LUAN

摘要

We present our experimental High Dynamic Range Imaging activities developed at Laboratoire Universitaire d'Astrophysique de Nice (LUAN). They comprise experimental results with Phase Knife and Four Quadrant Phase Masks prototypes. This research will contribute to define future high dynamic range instruments equipping ground-based (e.g. VLT-Planet Finder) or space-based (e.g. DARWIN/TPF) observatories.
