Abstract
MATISSE (Multi-AperTure mid-Infrared SpectroScopic Experiment) is a mid-infrared spectro-interferometer project combining up to four UTs/ATs beams of the VLTI. It will measure closure phase relations, thus offering the capability for image reconstruction. The VLTI offers the possibility to position the Auxiliary Telescopes at several different stations, which gives much better uv-coverage than fixed telescopes. We carried out simulated observations with MATISSE, in order to find out the requirements for efficient image reconstruction. In particular, we study how many different telescope configurations are necessary to obtain sufficient coverage of the uv-plane. We analyse which stations are the most important for an optimal uv-coverage. We also examine which measurement precision is necessary to reconstruct images suitable for the science goals of MATISSE.
