Abstract
Results of experimental studies of detector arrays scintillator-photodiode (S-PD) and scintillator-photoreceiving device (S-PRD) used for X-ray digital radiography have shown that there exist further possibilities to increase spatial resolution of this system up to 2-3 line pairs per mm. Theoretical analysis and experimental studies show that the two-energy detection method not only allows one to detect organics on the background of metal, but also substantially increases (by 3-5 times) the detection ability of the system as a whole, especially if parameters of the S-PD pair are optimized, in particular, when ZnSe(Te) is used in the low-energy circuit. A possibility to distinguish, in principle, between substances with insignificant differences in atomic number has been theoretically proven-by transition to multi-energy radiography. 3D-imaging has been realized using S-PD detector arrays. On base of theoretical and experimental search was installation of several types of inspection systems for control objects with square size 0.4Ã0.6-2.5Ã3.5Â m.
