Abstract

L'invention concerne un système et une méthode pour inspecter un tube de reformeur utilisé dans un traitement chimique. Cette inspection est destinée à détecter le fluage et l'effusement métallique du tube. La méthode de l'invention comprend les étapes consistant à: focaliser un faisceau lumineux cohérent sur l'intérieur d'un tube ou d'un conduit et détecter au moins une partie d'un reflet du faisceau lumineux provenant du tube, en convertissant le faisceau lumineux détecté en un signal électrique, puis traiter le signal électrique pour déterminer un rayon du tube soumis à l'inspection in situ.
