Paper Abstract

The analysis of transient processes (TP) is facing information processing systems with more and more complex tasks. At present it is the measurement of the spatial distribution of the objects' internal heterogeneity and their temporal variation which is focusing the attention of researchers. The tomographic method (1) makes it possible to obtain the distributions of the absorption coefficient or the refractive index over the cross-section of a three-dimensional object. Tomography is a two-stage process. In the first stage the object under study is probed by penetrating radiation at different camera angles (aspects), and the field of the transmitted wave (the so-called projection) is recorded.
