The invention relates to a device for optical inspection of the open surfaces (19 of objects from at least two different viewing directions (P1, P2). The device comprises a telecentric imaging unit (11 or 12, an angle mirror (13) and auxiliary mirrors (8) within the area (K) of the telecentric imaging unit, between this and the object. The object is placed between the arms (3a, 3b) of the angle mirror (13) and the telecentric imaging unit is directed towards the combination of object and angle mirror. Said auxiliary mirrors (8) have been oriented and positioned at intervals from the telecentric imaging unit such that the differences of distance of the viewing directions (P1 and/or P2 and/or P3 and/or P4) via the two arms (3a and 3b) of the angle mirror or via one arm (3a tai 3b) or not via the arms are compensated as they pass via said auxiliary mirrors.

L'invention porte sur un dispositif d'inspection optique des surfaces ouvertes (19) d'objets à partir d'au moins deux directions d'observation différentes (P1, P2). Ce dispositif comprend une unité d'imagerie télécentrique (11 ou 12), un miroir d'angle (13) et des miroirs auxiliaires (8) dans la zone de (K) de l'unité d'imagerie télécentrique, entre celle-ci et l'objet. Cet objet est placé entre les supports (3a, 3b) du miroir d'angle (13) et l'unité d'imagerie télécentrique est orientée en direction de l'objet et du miroir d'angle. Ces miroirs auxiliaires (8) ont été orientés et positionnés à certains intervalles de l'unité d'imagerie télécentrique si bien que les différences de distance des directions d'observation (P1 et/ou P2 et/ou P3 et/ou P4) au moyen des deux supports (3a et 3b) du miroir d'angle ou au moyen d'un support (3a ou 3b) ou sans les supports, sont compensées lorsqu'elles passent par les miroirs auxiliaires.
