Abstract: High contrast imaging appears to be not only the most promising technique to explore the outer regions of extrasolar planetary systems, giving us a view of a complementary separation domain, but will also give us information on their atmospheres. The possibility of coupling an integral field spectrograph to a module for extreme adaptive optics and a 8m class telescope is already on the way (SPHERE for VLT and GPI for South Gemini), focusing on young giant planets. The possibility for similar instrumentation on ELTs (EPICS) is under study, and this will give us a much more complete view of extrasolar planetary systems, at different ages and, in some peculiar cases, reaching the habitable zone. A second order characterization of planets already discovered with other techniques will also be possible. In this framework we present the advantages and limits of the high contrast imaging technique and the potential of EPICS in characterization of atmosphere of both Jupiter-like and Earth-like planets using high resolution spectroscopy (R∼ 3000 and R∼ 20000).
