Abstract
L'INVENTION CONCERNE UN FILTRE CHROMATIQUE FONCTIONNANT PAR DIFFRACTION. CE FILTRE COMPREND UN ENSEMBLE LENTICULAIRE 100 A PERIODICITE DE LENTILLES L, A LONGUEUR FOCALE F ET A OUVERTURE RELATIVE F, ET UN RESEAU DE DIFFRACTION 108 DE PAS DL (LONGUEUR D'ONDE DE LA LUMIERE POLYCHROMATIQUE TRAITEE). DANS LE PLAN FOCAL DE L'ENSEMBLE LENTICULAIRE, SE TROUVE UNE SURFACE PHOTOSENSIBLE 106 QUI RECOIT UNE IMAGE PAR L'INTERMEDIAIRE D'UNE LENTILLE 100. APPLICATION AUX CAMERAS DE TELEVISION EN COULEUR A UN SEUL TUBE.
