In the paper, studies of fiber transmission lines have been considered, for measurements of distances in space and atmosphere, the study of atoms and molecules and in solving other problems of science and technology. The article deals with one of the pulse methods of fiber optics, i.e. scatterometry or backscattering for metal surfaces qualitative parameters control. This object can be apply not only to radio electronics, but also to physics, chemistry, biology and other areas of science and technology.
