Abstract
L'invention concerne un détecteur où au moins une tête (16) de détection de radiations est disposée au voisinage d'un champ (20) de vision pour détecter des radiations provenant du champ (20) de vision. La tête (16) de détection de radiations comprend un collimateur (60), comprenant une ouverture (62) à travers laquelle passent les rayons des radiations émanant du champ (20) de vision, et un système (44) de détection formant une surface (68) arquée dont le foyer est situé sur l'ouverture (62) du collimateur servant à détecter les radiations de telle sorte que les rayons des radiations reçus à travers l'ouverture (62) du collimateur frappent la surface arquée sensiblement perpendiculairement à une aire incrémentale de la surface (68) arquée.
