Abstract

This paper exposes a method for evaluating the performances of a systemdedicated to exoplanet direct imaging. It is based on the use of a statisticaldescription of a somewhat ideal star/planet couple in terms of contrast and angular separation.Among many already available techniques, the Phase Induced Amplitude ApodizationCoronagraph (PIAAC) seems to gather all the necessary qualities to performdirect imaging of hypothetical Earth-like exoplanets in the close Solarneighbourhood (30 pc).After a quick description of its concept, the proposed evaluation method is used and provides an original set of criteria to classify concepts.
