CA 2504335

A wiring pattern inspection device includes: a light source (10); a parallel light guide section for guiding light from the light source substantially parallel; and light extraction section for extracting a transversal wave light component orthogonally intersecting the guided light direction, converting the transversal wave component into a particular polarized component, applying the particular polarized component to a work (51), and extracting a longitudinal wave light component from the reflected light of the particular polarized component reflected from the work.

L'invention concerne un dispositif de contrôle d'un modèle de câblage, comprenant une source lumineuse (10), une section de guidage parallèle de la lumière destinée à guider la lumière de la source lumineuse de manière sensiblement parallèle, et une section d'extraction de la lumière destinée à extraire une composante lumineuse à onde transversale croisant de manière orthogonale la direction de la lumière guidée, à convertir la composante à onde transversale en une composante polarisée spécifique, à appliquer la composante polarisée spécifique sur un élément (51), et à extraire une composante lumineuse à onde longitudinale de la lumière réfléchie de la composante polarisée spécifique réfléchie à partir dudit élément.
