Core-Ring-Ratio Method For Surface Roughness Measurement
Abstract
With a simplified statistical model,the relation between the light energy and the surface roughness is deduced for the case that a laser (or incoherent) beam incidents on a rough surface, wherefrom a rather simple method for surface roughness measurement is presented.
