Abstract

In this paper we present some preliminary simulations concerning adaptive-optics-aided coronagraphy. The starting point used for this goal is the software system CAOS (Code for Adaptive Optics System), because of the simulation design ease given by its graphical programming environment, and the completeness and flexibility of its set of modules dedicated to adaptive optics (AO) simulations. We have so developed the complementary numerical tools necessary to implement the Coronographe Interférentielle Achromatique (CIA) within CAOS, together with differential imaging, and considering Fresnel propagation through the turbulent atmosphere. Hence we give an example of application to exoplanet detection with the characteristics of the Very Large Telescope AO system NAOS and the CIA. Finally, we also discuss on some other recent developments concerning CAOS.
