Abstract

L'invention concerne un dispositif pour former des franges parfaitement contrastées et à grande luminosité, utilisable notamment dans l'infrarouge. Ce dispositif comprend un dédoubleur achromatique D permettant, à partir d'une source étendue, de produire deux images homologues étendues S1 , S2 , un miroir sphérique concave M réfléchissant les rayons issus de ces deux images pour produire des franges d'interférence sur un moyen de réception et/ou d'analyse disposé entre ledit miroir sphérique et les images homologues, le centre de courbure C du miroir sphérique concave étant situé sur l'axe du système optique et dans le plan défini par les images homologues. Utilisation de ce dispositif notamment à la spectrophotométrie interférentielle à modulation sélective.
