Abstract

L'invention propose aux fins du contrôle optique d'articles en verre creux (1) un ensemble de contrôle constitué d'une source de lumière (3), d'au moins une caméra (6) et d'une position de contrôle (7) installée entre un filtre de polarisation (4) passif et un filtre de polarisation (5) actif. En fonction du niveau de polarisation réglable par un signal électrique du filtre de polarisation (5) et ajustable par rapport à celui du filtre de polarisation (4) selon un angle de π/2, le chemin optique entre la source de lumière (3) et la caméra (6) forme un ensemble de lumière transmise ou un ensemble de contrainte de lumière transmise de sorte que peuvent être relevés par un pilotage correspondant du filtre de polarisation (5) différents défauts de l'article en verre creux (1), tels que des inclusions, dommages superficiels et zones de tension à l'intérieur de la structure du matériau.
