DETERMINING SURFACE ROUGHNESS

Determining Surface Roughness A measurement system (301) for determining surface roughness is shown. A coherent illumination device (303) illuminates the surface of, for example, a component (201) with coherent light. An imaging device (304) 5 obtains an image of speckle caused by the scattering of...
