Paper Abstract

We have built at the Haute-Provence observatory (France) the rst diluted telescope in the world. We describe this prototype called Carlina, made of three 25 cm mirrors separated by a maximum baseline of 10.5 m. The three mirrors in place are already coherenced and rst light is scheduled for June-July 2012. In this article, we will mainly describe the focal gondola. We propose to build in the near future a 100 m aperture Large Diluted Telescope. This diluted telescope will be more sensitive than regular interferometers (Keck, VLTI, etc.), with higher imaging capabilities. A LDT will open new elds of research in astrophysics thanks to very high angular resolution imaging of the surface of supergiant stars, AGN, gravitational micro-lens systems, exo-planets, etc.
