Interferometric telescope system in which at least two polychrome beams (5, 6) coming together from the same celestial object interfere and form several Airy's disks in the focal plane (4) of the said system. According to the invention, the telescope system is characterized: by the fact that it includes a light disperser (in 14) separating it on the basis of wave length and arranged on the trajectory of the said polychrome beams in the vicinity of the said focal plane (4); and by the fact that the said light disperser arranges, in the said focal plane (4), the said monochrome Airy disks at least approximately adjacent in an alignment parallel to the alignment of their interference bands.

Système de téléscope interferométrique dans lequel au moins deux faisceaux polychromes (5, 6) provenant ensemble d'un même objet céleste interfèrent et forment plusieurs taches d'Airy dans le plan focal (4) dudit système. Selon l'invention, le système de téléscope est caractérisé: en ce qu'il comporte un disperseur de lumière (dans 14) séparant celle-ci en fonction de la longueur d'onde et disposé sur le trajet desdits faisceaux polychromes au voisinage dudit plan focal (4); et en ce que ledit disperseur de lumière arrange, dans ledit plan focal (4), lesdites taches d'Airy monochromes de façon au moins approximativement adjacente en un alignement de direction parallèle à celle de leurs franges d'interférence.
