Results presented in Figure 2 show that white light interferometry
measurement of both the ball and disc sample is essential to interpret the true wear situation from any ball-on-flat tribocouple.
Die plug analysis, chloroform washing of the co-PET layer and white light interferometry were used for experimental validation of CFD results.
For final film interpretation, the co-PET thickness values were compared with both the white light interferometry thickness values and the CFD co-PET flow values.

The contours formed by white light interferometry allow Bruker testers to determine whether surface damage consists of pits, scratches, spirals, etc.
Examining devices by the nanometer, which is one-billionth of a meter, is one thing, but scientists at Bruker can drill down to the angstrom level--one ten-billionth of a meter--with white light interferometry. Thus, Bruker is able to avoid getting slowed down by the slicker polymers and more resistant materials taking longer to show wear.

Vertical-scanning white light interferometry is a widely used technique of profiling the surface topography of objects such as semiconductors, liquid crystal displays (LCDs), and so on.
The objective of this study was to investigate and analyze wear in a commercially available 3.6L V6 gasoline engine and evaluate the wear of the piston rings and piston ring/liner interface with a market representative fuel containing a generic additive using radioactive tracer technology (RATT) and white light interferometry

Using white light interferometry
and a precision motorized stage, the NanoMapper can create 3-D nanotopology wafer maps with unmatched height resolution and stitch them together for an expanded field of view.
Zygo Corp., Middlefield, CT, has incorporated its MetroPro analytical software for scanning white light interferometry
into New View 100, its 3-D imaging surface structure analyzer.
