High angular resolution imaging is an increasingly important capability in contemporary astrophysics. Of particular relevance to emerging fields such as the characterization of exoplanetary systems, imaging at the required spatial scales and contrast levels results in forbidding challenges in the correction of atmospheric phase errors, which in...

The VLTI has a huge potential for the study of Active Galactic Nuclei. It allows to resolve the BLR by phase differential interferometry and to make images of the inner dust « torus ». The first generation VLTI instruments AMBER and MIDI allowed studies of the size-luminosity of the inner dust structures and showed strong departures from the...
