COATING AND WALL THICKNESS ANALYSIS
By imaging objects in 3D, X-ray CT (computed tomography) can analyze coating and wall thickness distribution. Owing to its non-destructive nature, internal coatings and walls that cannot be accessed from the outside can be analyzed. This technique is applied to golf ball shells, tablet coatings, bottle caps, foam cell walls, etc.
The surface of the coatings or walls is defined either by the ISO-50 surface determination or image segmentation technique. Then the surface mesh is defined. Lastly, the thickness is calculated as either the shortest distance between the two surfaces (for relatively uniform walls) or as the largest sphere that can fit between the walls (for irregularly shaped walls.)
