Principle of Measurement. Let us consider the physical foundations of the technique. Note that the technique utilizes
the fact that the x-ray image, a plane distribution of radiation intensity, may be formed and transmitted for some distance
by means of Kumakhov optics [5–9]. As has already been noted, Kumakhov optics constitutes a collection of tubes,
usually of glass, formed into beams of different configurations [5–7]. Note that the basic characteristics of the variation in
the propagation of x-radiation that is achieved, in particular, the production of convergent, parallel, and divergent beams,
depends on the form of the particular configuration.
