For reconstruction of the spatial structure of many-component objects, it is proposed to use multi-radiography with detection of X-ray by combined detector arrays using detectors of ``scintillator-photodiode'' type. A theoretical model has been developed of multi-energy radiography for thickness measurements of multi-layered systems and systems with defects. Experimental studies of the sensitivity, output signal of various inspection systems based on scintillators ZnSe(Te) and CsI(Tl), and object image reconstruction (with organics and non-ogranics materials singled out) have been carried out.
