The backscatter X-ray inspection system of the sole uses the Compton scattering effect between the X-ray and the substance. Using the principle of point scanning imaging, the inspected person stands on the backscattering inspection table of the sole, and the security personnel perform manual work on the inspected person. At the same time of searching, the X-rays scattered by the backscattering tester generate a clear back-scattered X-ray image of the sole of the examinee. The backscattered image is opposite to the ordinary fluoroscopic image, and can highlight substances composed of low atomic number elements, especially A substance rich in hydrogen, oxygen, carbon, and nitrogen. Since both explosives and drugs belong to such organic matter, the scattering ability to X-rays is strong, the scattered signals collected are strong, and the gray scale of the image is relatively bright. Therefore, the backscatter X-ray inspection equipment can find the sole carrying Dangerous goods such as explosives. At the same time, metal objects, such as blades and daggers, have low scattering power for X-rays, low received signals, and black in the image. These dangerous weapons carried by the soles are also easily found in the background of human body scattering. This equipment has independent intellectual property rights and has obtained national invention patent (patent number: 20160565646.3). It has a unique fast backscattering flying point scanning mechanism to ensure high-definition backscattering images, ultra-low radiation dose, free of shoes, and fast by.
