Presentation 1 : Oral
coronographie à masque de phase
P. Riaud, D. Rouan, A. Boccaletti, J. Baudrand
We presente various coronagraphic techniques and more precisely
the four quadrants phase mask (FQ-PM). After presentation of preliminary laboratory results where we obtain 33000 of rejection factor on the central peak, we develope the possible ground-based test of FQ-PM with VLT or CFHT telescope.
This study calls up futur developements for the "Planet Finder" project.
