Installed at the heart of the Very Large Telescope Interferometer (VLTI, located on top of the Cerro Paranal, in northern Chile), the VINCI instrument allows to combine coherently the infrared light coming from two separate telescopes. Therefore, it opens an access to very high angular resolution observations of the sky (down to a few milliarcseconds). Many important astrophysical questions will be adressed by this instrumen t: the physics of stars, protoplanetary disks and extrasolar planets, among other programs. My thesis work on the VINCI instrument has covered its conception, in particular the functionnal definition of its software system, its installation on top of the Cerro Paranal and its first scientific observations. In the first ...
