Abstract[English]
A viewing device (210) is configured to magnify and view a marking on a gemstone. The viewing device includes a light source (244), a mask (248), a magnifying optical device (206), and a camera (258). The light source generates light directed along a first path towards the gemstone. The mask partially obscures the light from the light source to generate a pattern. The partially obscured light is reflected off of the gemstone and magnified by the magnifying optical device. The camera is positioned to capture the magnified light. One or more additional light sources generate light directed along a second path towards the gemstone. The light enters the gemstone through a preferred facet and internally reflects. Internally reflected light scatters off of an internal mark in the gemstone and exits the gemstone through the gemstone's top face. The reflected and scattered light is magnified by the magnifying optical device and captured by the camera.[French]
L'invention concerne un dispositif de visualisation (210) configuré pour agrandir et visualiser un marquage sur une pierre précieuse. Le dispositif de visualisation comprend une source de lumière (244), un masque (248), un dispositif optique grossissant (206) et une caméra (258). La source de lumière génère de la lumière dirigée le long d'un premier chemin vers la pierre précieuse. Le masque occulte partiellement la lumière provenant de la source de lumière pour générer un motif. La lumière partiellement obscurcie est réfléchie par la pierre précieuse et amplifiée par le dispositif optique grossissant. La caméra est positionnée de manière à capturer la lumière amplifiée. Une ou plusieurs sources de lumière supplémentaires génèrent de la lumière dirigée le long d'un second chemin vers la pierre précieuse. La lumière pénètre dans la pierre précieuse par une facette choisie et se reflète à l'intérieur. La lumière réfléchie intérieurement se diffuse d'une marque interne dans la pierre précieuse et sort de la pierre précieuse par sa face supérieure. La lumière réfléchie et diffusée est amplifiée par le dispositif optique grossissant et capturée par la caméra.
