Abstract
Dispositif de détection du rayonnement d'un objet, pour la détermination des irrégularités ou des défauts d'une face de l'objet, au moyen d'un appareil de scrutation et de détection. L'appareil reçoit le rayonnement par une fente d'un écran, ladite fente étant de largeur variable et étant inclinée par rapport à la direction de déplacement de l'objet qui passe au-dessous de la fente. L'invention s'applique en particulier à l'examen qualitatif du bois, lors du sciage.
