FIELD: physics. ^ SUBSTANCE: disclosed is a system for inspecting luggage using an X-ray image. The image is formed in transmitted light using a fan beam and a segmented array of detector elements (segmented sensor array) and a scanning narrow beam is used to obtain the image in diffused light. Both beams act simultaneously. Interference between the beams is suppressed by combining such factors as screening, design, arrangement and alignment of the diffused radiation (back-scattered) light sensor, as well as the corresponding image processing. During image processing, the measured beam intensity value of the subsystem for image formation in transmitted light is subtracted from that scattered onto detectors of the subsystem for image formation in diffused radiation (back-scattered). ^ EFFECT: possibility of reducing interference of X-ray radiation in two subsystems using transmitted and diffused light in one compact image formation system. ^ 28 cl, 3 dwg |
