Abstract

Dispositifs détecteurs de rayonnement infrarouge. Au moins une partie de la surface 8 d'un élément pyroélectrique 5 qui reçoit le rayonnement 7 comporte, un film 4 de haut polymère, et présente un profil courbe. Dans le cas de l'exemple considéré, l'élément occupe une partie de la surface latérale d'un support cylindrique 6 qui est avantageusement choisi transparent au rayonnement infrarouge. Application aux détecteurs de rayonnement infrarouge, pour en améliorer la sensibilité dans diverses directions.
