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 thecompleteness 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 CoronographeInterférentielle Achromatique (CIA) within CAOS, together with differential imaging, andconsidering Fresnel propagation through the turbulent atmosphere. Hence we give an example ofapplication to exoplanet detection with the characteristics of the Very Large Telescope AO systemNAOS and the CIA.Finally, we also discuss on some other recent developments concerning CAOS.
