Paper Abstract

The array concept for ESO's Very Large Telescope (VLT) project opens the possibility of observations with very high angular resolution. The long baseline provides a resolution span from approx. 0.5 marcsec in the blue to approx. 30 marcsec at 20 um wavelength. Realistic target for the interferometric operation is the IR range from 5 to 20 pm and later a gradual expansion to shorter wavelengths. In the interferometric mode the gain of the 8 meter single apertures of the VLT is only given if adaptive optics is applied for a real-time partial or full phase compensation of the degradations due to atmospheric turbulence,
