Abstract

Un appareil de contrôle de surface permet d'inspecter une surface de forme complexe telle que la surface de peinture d'une voiture, et comprend un laser (31) fournissant un faisceau (26) de rayonnement, un organe d'exploration (39) permettant de balayer le faisceau sur la surface, un matériau rétroréfléchissant étant prévu pour réfléchir le long de la trajectoire du faisceau incident le rayonnement réfléchi depuis la surface, l'appareil comportant le matériau rétroréfléchissant étant monté comme une unité à déplacer au-dessus de la surface de la voiture à l'aide d'un robot. L'analyse du signal lumineux révèlera des défauts tels que rayures, inclusion de peinture, peau d'orange, pulvérisation sèche, bosses et défauts de brillants, et permettra de distinguer les défauts des caractéristiques qui doivent être présentes sur la surface telles que des craquelures de portières.
