Abstract

DISPOSITIF POUR LA DECOMPOSITION SPECTRALE D'UN FAISCEAU ELECTROMAGNETIQUE PARALLELE, COMPORTANT UN RESEAU A ECHELONS PAR REFLEXION, MUNI DE FACES REFLECHISSANTES, UN MECANISME DE VARIATION DE L'ANGLE D'INCIDENCE DU FAISCEAU PAR RAPPORT A LA NORMALE AUX FACES D'ECHELON ET UN MONTAGE DE SORTIE POUR LE TRAITEMENT D'UNE PARTIE DU FAISCEAU, REFLECHIE ET SELECTEE SPECTRALEMENT PAR LE RESEAU A ECHELONS. LE MECANISME DE VARIATION DE L'ANGLE D'INCIDENCE EST REALISE DE FACON QUE L'ANGLE PLAN FORME PAR LA DIRECTION D'INCIDENCE 16 ET LA NORMALE AUX FACES D'ECHELON 12 SE SITUE DANS UN PLAN, DONT L'INTERSECTION AVEC LE PLAN D'UNE FACE D'ECHELON EST AU MOINS SENSIBLEMENT PARALLELE AU GRAND AXE DES ECHELONS.
