Scientific paper
The mid-infrared spectral regime is of special interest for the detection of extra solar planets since the ratio of the planets flux over the flux of the host star is larger than at other wavelengths. Direct detection needs also high angular resolution in order to separate the planets signal from the star. High angular resolution at mid-infrared wavelengths - this is also the challenge met by MIDI - the MID-Infrared interferometric instrument - the first scientific instrument which is coming currently into regular operation at the ESO Very Large Telescope Interferometer on Paranal. This instrument is the first interferometric instrument for the mid-infrared range, which combines the light of two 8m-class telescopes in a direct way. Therefore it provides high sensitivity together with the advantage of spectral analysis of the source in a range from 8 to 13 micron. After MIDI successfully demonstrated its function by obtaining First Fringes in December 2002 it is now in the phase of commissioning. Here we scetch the current state of the commissioning and present some of the first results.
