Abstract
In this work an improved method of polychromatic X-raying for samples of composite structure is offered. During image processing, the exact spectral characteristics of source, detector and substances are taken into account, and the digital filtration of stray signals from scattered radiation is applied. From the experimental data, with the help of detector and calibration media spectra, the spectral structure of radiation for pulse X-ray devices with a cold cathode is determined. Use of the developed techniques allows one to reduce the number of calibrations, increase the accuracy of measurements of quantity for each component, and determine the quantitative distribution of different substances in space by the reduced number of images.
