Abstract

Il s'agit d'un dispositif pour l'exploration bidimensionnelle dans le domaine des longueurs d'onde infrarouge, comportant un système d'objectif, un détecteur sensible au rayonnement et un premier élément d'exploration appliqué entre le système d'objectif et le détecteur. Entre le premier élément d'exploration et le détecteur sont prévues deux voies de rayonnement comportant chacune un deuxième élément d'exploration et un objectif intermédiaire. Du fait que la longueur d'exploration du second élément d'exploration dans la première voie de rayonnement est supérieure à celle du second élément d'exploration dans la seconde voie de rayonnement et que l'objectif intermédiaire respectivement de la première voie de rayonnement, et la seconde voie de rayonnement provoque une représentation respectivement agrandie et réduite dans le plan focal du système d'objectif, il est possible d'effectuer une exploration avec deux champs de vision sans variation de l'ouverture du système d'objectif. Application : dispositif de balayage bidimensionnel pour l'infrarouge.
