Qu’est-ce que l’instrument MIRS ?<\/b><\/h4>\n

<\/b><\/p>\n

MIRS est un spectrom\u00e8tre imageur infrarouge: il conjugue les techniques de spectroscopie et d’imagerie en associant un spectre \u00e0 chaque point de l’image.<\/h5>\n

 <\/p>\n

MIRS fonctionne en mode \u00ab\u00a0pushbroom\u00a0\u00bb: il acquiert un champ lin\u00e9aire et disperse la lumi\u00e8re de chaque point de cette ligne pour enregistrer son spectre.\u00a0 <\/span>MIRS envoie donc au sol des images qui sont des \u00ab\u00a0lignes dispers\u00e9es\u00a0\u00bb.<\/h6>\n
