Surface Wear Subtraction Using 3D Profilometry

In this application the Nanovea ST400 Profilometer is used to measure the surface wear of a golf ball before and after wearing of the surface with sandpaper. The two profile measurements were then combined through software surface subtraction to analyze wear volume loss. This feature is ideal for applications such as but not limited to: wear, corrosion and lubrication failure.
