Abstract

FIELD: nondestructive testing of object internal structure by generation of image in flux of penetrating radiation. SUBSTANCE: invention is based on the fact that flux 4 of penetrating radiation with local angular spread limited by means of collimator 3 is passed through object 5. Radiation flux 6 passed through examined object 5 is recorded by direct selective detector 10 with width of directional pattern not exceeding double value of local angular spread of flux 4 of penetrating radiation to form image. In this case, local limitation of radiation flux 4 is carried out in two mutually crossing planes. EFFECT: increased efficiency. 9 cl, 7 dwg

Изобретение относится к способу неразрушающего контроля внутренней структуры объекта путем получения изображения в потоке проникающего излучения, основанному на том, что поток проникающего излучения 4, имеющий ограниченную с помощью коллиматора 3 локальную угловую расходимость, пропускают сквозь объект 5, для создания изображения регистрируют прошедший через исследуемый объект 5 поток 6 излучения дирекционно-селективным детектором 10 с шириной диаграммы направленности не более удвоенной величины локальной угловой расходимости потока проникающего излучения 4. При этом локальное ограничение потока 4 излучения ведут в двух взаимно пересекающихся плоскостях.

The invention relates to a method for non-destructive testing of the internal structure of an object by acquiring an image in a penetrating radiation stream, based on the fact that the penetrating radiation stream 4, having a local angular divergence limited by collimator 3, is passed through object 5, and the image transmitted through the object under study is recorded 5 radiation flux 6 by a directional selective detector 10 with a radiation pattern width no more than twice the value of the local angular divergence of the flux penetrating radiation 4. In this case, a local restriction of the radiation flux 4 is carried out in two mutually intersecting planes.
