WebApr 6, 2024 · Consequently, though mean roughness can easily be captured through one—or a few—profiles for standard manufacturing processes (those which leave a single texture orientation), optical areal measurement becomes mandatory to properly evaluate the surface in many cases. WebIntroduction to Surface Roughness and Scattering. The subjects of this book are surface roughness, primarily of optical surfaces, and light scattering. The type of scattering is classical scattering, not inelastic scattering such as Raman scattering. We have chosen to use the word roughness rather than the more general term texture, which is ...
