Title (EN) ENGINEERED VIDEO INSPECTION LIGHTING ARRAY
(FR) APPAREIL D'ECLAIRAGE POUR CONTROLE VIDEO
Abstract:
(EN) An engineered video inspection lighting system includes a three-dimensional array (22) of solid-state light emitting diodes (18) focused to an inspection area. A single high-current, low-duration pulse is applied to selected elements of the array. Light thus generated is passed through a diffuser (26) and to a specimen (D). Light reflected from the specimen is received by a lens (32) of a video camera (34) disposed in an interior of the three-dimensional array (22). Data thus obtained is used to determine acceptability of the specimen in accordance with preselected standards.
(FR) Un système d'éclairage pour contrôle vidéo comprend un réseau tridimensionnel (22) de diodes électroluminescentes (18) focalisées sur une zone de contrôle. Une seule impulsion à courant élevé et de courte durée est appliquée à des éléments sélectionnés du réseau. La lumière ainsi générée est transmise à travers un diffuseur (26) vers un spécimen (D). La lumière réfléchie par le spécimen est reçue par un objectif (32) d'une caméra vidéo (34) disposée à l'intérieur d'un réseau tridimensionnel (22). Les données ainsi obtenues sont utilisées pour décider si le spécimen peut être accepté en fonction de normes présélectionnées.
