摘要: A method of examining an object containing a polycrystalline material, in which at least one part of the surface of the object is illuminated with substantially isotropic light, as well as a illumination device for carrying out the method. In this manner, the polycrystalline material is less influenced by the different reflection characteristics of individual particles of the polycrystalline material.
