METHOD FOR DETERMINING THE SPATIAL PROFILE OF THE INSPECTED OBJECT Russian patent published in 2023 - IPC G01N23/203 

FIELD: automatic radioscopic control of moving objects.

SUBSTANCE: determining the spatial profile of the inspected object. The inspected object is irradiated with a narrow probing X-ray beam, the backscattered radiation is recorded by ionizing radiation detectors, while the logical signals from each ionizing radiation detector are accumulated in the synchronization system and interfaces during the formation of a single pixel of the radiographic image synchronously with the movement of the probing beam over the surface of the inspected object, the data accumulated within one pixel of the radiographic image is sent to the processor, whereas for each pixel of the radiographic image, the signals from different detectors of ionizing radiation are combined into groups, whereas based on the signals from each group, the difference and total signal are calculated, and by magnitude and the sign of their ratio, the component of the normal vector of the scattering surface is calculated, after which a pseudo-spatial profile of the inspected object is formed on the imaging device by displaying the normal vector component using the light-and-dark coding of the pixel.

EFFECT: providing the possibility of obtaining a spatial pseudo-3D profile of a high-quality inspection object.
