Influence of Curved Surface Roughness on White Light Interferometer Microscopy
Physics Education, v57 n1 Article 015001 Jan 2022
We outline the basic theory behind white light interferometry and the workings of a typical light interferometer microscope. We study WLI images obtained for rough and smooth chrome steel spheres to illustrate the principle that curved rough surfaces can be imaged with such a device as long as the surface roughness is kept within certain limits.
