Abstract: Abstract We introduce an optical 3D sensor that can measure the shape of objects with rough surface. The proposed sensor is based on white-light interferometry but it does not require a mechanical movement of the… read more here.

Abstract: 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… read more here.
