Webthe highest surface slope that can be measured by a far-field 3D imaging optical surface measuring instrument is the arcsine of the numerical aperture (NA) of the objective lens, … 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-
