Optical measurement of surface topography pdf
WebMar 31, 2011 · The measurement and characterisation of surface topography is crucial to modern manufacturing industry. The control of areal surface structure allows a manufacturer to radically alter the functionality of a part. Examples include structuring to effect fluidics, optics, tribology, aerodynamics and biology. To control such manufacturing … Webmethods are quite different. These methods sense an area of the surface as a whole and provide a measure of the overall surface roughness of that area, perhaps even with a single measured parameter. The most widely used of these methods are based on light scattering. We illustrate two important types of light scatter meth-
