Abstract

La présente invention concerne un dispositif d'inspection d'œufs (1) qui est pourvu de : un élément de maintien (62) pour maintenir un œuf (E) ; des parties d'irradiation (2, 3) pour irradier l'oeuf (E) avec de la lumière ; des parties de capture d'image (4, 5) pour capturer une image de l'œuf (E) irradié avec la lumière ; et une partie de détermination (7) pour déterminer des conditions de surface de l'œuf (E). Les parties d'irradiation (2, 3) sont pourvues d'éléments d'inclinaison (21, 31) et d'éléments électroluminescents (22, 32). Les éléments électroluminescents (22 32) ont des surfaces électroluminescentes, qui sont affleurantes avec les surfaces des éléments d'inclinaison (21, 31), et émettent de la lumière. Les éléments d'inclinaison (21, 31) sont inclinés de sorte que les surfaces des éléments d'inclinaison (21, 31) sont orientées vers l'œuf (E) maintenu par l'élément de maintien (62).
