METHOD OF RADIATION COMPUTATIONAL VIBROTOMOGRAPHY Russian patent published in 1998 - IPC

FIELD: study of materials and objects by methods of radiation computational tomography. SUBSTANCE: method consists in inspection of at least one layer of examined object by beam of penetrating radiation, in registration of radiation passed through object by detection system, in primary processing of signals of detection system with generation of measurement signals, in processing of measurement signals with generation of set of reconstructive data and in reconstruction of image of layer of examined object. As result of primary processing of signals there is extracted one variable component of mentioned signals as minimum on one frequency of vibrations of examined object and set of reconstructive data is obtained on the basis of extracted variable component. EFFECT: method ensures possibility of study of dynamic periodic processes going on in objects with structures closed for mechanical or optical access. 6 cl, 1 dwg
