| Popis: | Dynamic radiography is a high resolution technique using finely collimated radiation detectors to analyze the scattered component of penetrating radiation (e.g. x-rays, gamma rays, and neutrons). Inherent or induced periodic motions (vibrations) within a subject produce a complex modulation pattern in the scattered radiation field. This modulation can be detected and used to locate the site of the perturbation, the amplitude of the motion, and the frequency components generated. Completed initial experiments demonstrate a resolution capability in the sub-millimeter range accompanied by detailed frequency information in a 0 to 100 hertz spectrum. |
