Direct imaging is crucial for atmospheric analysis of exoplanets.

Instrument capabilities vary in spectral and spatial resolution.

Abstract

With the ever-growing number of exoplanets detected, the issue of characterization is becoming more and more relevant. Direct imaging is certainly the most efficient but the most challenging tool to probe the atmosphere of exoplanets and hence in turns determine the physical properties and refine models of exoplanets. A number of instruments optimized for exoplanets imaging are now operating or planned for the short and long term both on the ground and in space. This paper reviews these instruments and their characteristics/capabilities. Conclusions are drawn on the spectral characterization point of view.
