Abstract

Pour mesurer des caractéristiques d'un revêtement de surface (1) d'une bande métallique en défilement, telles que le niveau d'alliation d'un revêtement comportant du zinc et du fer, on expose le dit produit au rayonnement (23) d'une source radiative (24) de longueur d'onde prédéterminée, dirigé orthogonalement à la surface du produit et on mesure l'énergie réfléchie par la dite surface, également selon une direction orthogonale à la surface, de façon à s'affranchir des variations de réflectivité dues à des caractéristiques morphologiques de la surface et on effectue ces opérations à l'aide de fibres optiques du commerce préalablement dépouillées à leur extrémités libres (21, 31) de leur optique de focalisation habituelle de manière à pouvoir être rapprochées au maximum l'une de l'autre et disposées parallèlement entre-elles.
