Abstract

L'invention concerne des procédés d'enregistrement d'un ou de plusieurs pixels d'énergie laser sur une surface de construction à au moins une source d'énergie laser de la pluralité de sources d'énergie laser et/ou de détermination d'un état de fonctionnement de la ou des sources d'énergie laser. Dans certains modes de réalisation, un détecteur photosensible peut capturer au moins une image de la surface de construction avec un ou plusieurs pixels d'énergie laser formés sur celle-ci. Une trame de référence du détecteur photosensible peut être enregistrée avec une trame de référence du ou des pixels d'énergie laser sur la base, au moins en partie, d'un emplacement identifié du ou des pixels d'énergie laser à l'intérieur de la ou des images. Ceci peut comprendre l'utilisation d'une fréquence spatiale caractéristique des pixels d'énergie laser à l'intérieur de la ou des images. Dans certains modes de réalisation, au moins une image comprenant un motif de soudure d'une partie formée peut être comparée à un motif de soudure attendu pour déterminer un état de fonctionnement de la ou des sources d'énergie laser pendant le fonctionnement.
