WebWall thickness measurement by the use of film density variations has also been applied occasionally, especially for images taken with radioactive isotopes, because here the influence of scattered radiation could be neglected. These procedures have so far been done by hand, the operator first measuring either the shadow projections of the wall ... WebIt can measure film thickness and density of multilayer samples. How it works — an X-ray beam is reflected off of a sample at very small diffraction angles generating a reflectivity pattern. A simulation of the reflectivity pattern gives an accurate measurement of thickness, interface roughness, and layer density for either crystalline or ...
