Abstract

L'invention a pour objet un tube de prise de vues thermique à cible pyroélectrique réticulée. La cible comprend un réseau d'éléments pyroélectriques 4 ayant chacun la forme d'un cube dont les flancs latéraux sont inclinés d'un angle alpha de manière que, à l'exception des éléments situés dans l'une des colonnes marginales et dans l'une des rangées marginales, le sommet de chaque élément surplombe, sur deux de ses flancs, la base d'un élément adjacent situé dans la même rangée et la base d'un élément adjacent situé dans la même colonne, de manière que la surface en surplomb de chaque élément soit exposée aux radiations venant frapper la région des canaux 6 séparant les éléments. L'invention trouve son application dans les caméras de télévision thermiques.
