FIELD: physics.
SUBSTANCE: apparatus for determining characteristics of material of analysed object has a first and a second bogie, each having a source of penetrating X-rays, having a collimator for forming a narrow beam directed onto the analysed object, at least one motor which is configured to move each bogie relative the analysed object so as to move the narrow beam relative the object in a direction having a vertical component and at least one sensor for detecting radiation back-scattered from the analysed object and generated by at least one of the radiation sources.
EFFECT: enabling design of a scanning system which combines high quality of images formed with high efficiency.
