| Abstract: | It is discovered that the detective display of the back scattering imaging technology, which uses flying spot scanning X-ray to de- tect, is more efficient than the transmission detective display, especially for slight and feathery narcotics and lamellate dynamite. The chopper wheel is the key element to achieve the back scattering imaging technology, which affects the imaging resolution of the detective system. Se - lection of the structure of the chopper wheel mechanism and the shielding material of the c... |
