Abstract

We briefly recall the characteristics and particularities of the optical recombination of the Solar Ultraviolet Network (SUN) experiment which consists in a non-redundant << compact >> array of 4 telescopes of 20 cm diameter aligned on a 2 meters linear baseline. We proceed to the evaluation of the geometrical and optical aberrations of the recombination outlining the difficulties inherent to interferometric systems (in particular, and forgotten up to now, the << cophasing condition >>).We conclude on the advantages linked to a compact system like SUN.
