Abstract

L'invention concerne un appareil de contrôle optique. Cet appareil comprend un plateau pour supporter un dispositif contrôlé et une source de lumière est prévue pour éclairer une partie arrière du dispositif. Cet appareil de contrôle comprend également une caméra placée sur une partie latérale avant du dispositif pour recevoir l'énergie optique qui pénètre par le dispositif et un diffuseur également placé sur une partie latérale avant du dispositif. La source d'éclairage fournit une image sur une surface de fond du diffuseur en vue de son traitement par la caméra.
