Abstract

Dispositif servant à détecter une image thermique, comportant un groupe d'éléments thermocapteurs de type pyroélectrique (5) agencés sur une rangée, un système optique (6), une structure (7) permettant de réunir en un seul corps le groupe d'éléments thermocapteurs de type pyroélectrique (5) et le système optique (6), et un arbre rotatif (8) faisant tourner la structure (7). Grâce à cette configuration, le système de détection d'images thermiques bidimensionnelles par l'utilisation du groupe d'éléments thermocapteurs de type pyroélectrique (5) agencés sur une rangée de manière unidimensionnelle présente une structure simple et peu encombrante.
