Abstract
(EN)
Disclosed is an inspection system (100) having a background (102) positioned adjacent an inspection zone (104); and an image capturing device (106) configured to receive background electromagnetic radiation (EMR) from the background and from the inspection zone, the inspection zone being configured and arranged to receive material for transport into the inspection zone; wherein the background has a background property defined by a background emission, a background absorbance, and a background reflectance, the background property being matched in EMR to a material EMR of material to be transported into the inspection zone, the material having a material property defined by a material emission, a material absorbance, and a material reflectance; and wherein the image capturing device is configured to detect a foreign object within material when transported into the inspection zone by deducting the background EMR from the material EMR.

L'invention concerne un système d'inspection (100) comportant un fond (102) positionné adjacent à une zone d'inspection (104) ; et un dispositif de capture d'image (106) configuré pour recevoir un rayonnement électromagnétique de fond (REM) à partir du fond et de la zone d'inspection, la zone d'inspection étant configurée et agencée pour recevoir un matériau à transporter dans la zone d'inspection ; le fond présente une propriété de fond définie par une émission de fond, une absorbance de fond et une réflectance de fond, la propriété de fond étant mise en correspondance dans le REM avec un matériau REM à transporter dans la zone d'inspection, le matériau présentant une propriété de matériau définie par une émission de matériau, une absorbance de matériau et une réflectance de matériau ; et le dispositif de capture d'image est configuré pour détecter un objet étranger dans le matériau lorsqu'il est transporté dans la zone d'inspection par déduction du REM de fond du matériau REM.
