Abstract

Les couleurs ou les états superficiels de petits articles sont déterminés en les faisant passer à travers une sphère d'une seule pièce et en les éclairant séparément avant leur entrée dans la sphère, au cours de leur passage à travers celle-ci et après leur sortie de la sphère. La lumière transmise ou réfléchie par chaque article est recueillie par la sphère et transférée à un appareil analyseur. Les articles sont triés conformément aux mesures.
