VISUAL INSPECTION SYSTEM AND VISUAL INSPECTION METHOD, NAMELY FOR INSPECTION OF THE EXTERNAL SURFACE OF NUCLEAR COMPONENTS

摘要

The inspection system for detecting a deposit on a surface (24) comprises: - a light source system (14) to draw a light pattern (20) onto at least a region of the surface (24); - an image capturing system (16) to capture a digital image (36) of the light pattern (20) drawn onto the region of the surface (24); and - a processing system (18) configured to digitally process the image (36) to determine the presence of a deposit on the region of the surface (24) affecting light reflection properties of the surface (24) as a function of the light pattern (20) drawn onto the region of the surface (24).
