X射线飞点扫描盘形狭缝斩波轮

X-ray Flying Spot Scans the Slot Chopper Wheel

研究表明X射线飞点扫描探测有机物背散射成像,特别是对少量且轻薄的毒品、薄型炸药的探测显示,比透射探测显示更加突出。斩波轮是实现X射线飞点扫描背散射成像技术的关键部件,影响探测系统的成像分辨率,斩波轮机构的结构和屏蔽材料选用,直接影响探测设备的工艺性能和使用性能。

It is discovered that the detective display of the back scattering imaging technology, which uses flying spot scanning X-ray to detect, 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 hack scattering imaging technology, which affects the imaging resolution of the detective system. Selection of the structure of the chopper wheel mechanism and the shielding material of the chopper wheel directly influence the processing property and functional performance of the whole detective equipment.
