White light interferometry (WLI) is a contact-free optical method for measuring surface height. It uses the phase difference between the light reflected off a reference mirror and the target sample to ...

Faster computer and electronic processors require smaller features for integrated circuits (IC), which in turn require smaller and smoother substrate surfaces. Chemical mechanical polishing (CMP) has ...

The concept of measuring surface roughness originated nearly a century ago as a means to prevent uncertainty and disputes between manufacturers and buyers. Now, it has become a common identifier used ...

The form of orthopedic implants can broadly vary. These variations can occur in terms of size (from millimeters to tens of centimeters), shape (from complex saddle-shaped knee prostheses to simple ...

Several advanced techniques have been used for 3D micro-surface profiling, such as white light interferometry, confocal microscopy, and atomic force microscopy. However, a major technological ...

Optical Profilometry employs light to measure surface contours and roughness by analyzing the interaction between light waves and the surface under examination. It utilizes various principles such as ...
