摘要
与透射辐射成像相比,康普顿背散射成像技术更适用于爆炸物、毒品等低密度违禁品的检测。据此,提出了一种大型客体阵列背散射辐射成像方案,设计、开发了一体化阵列气体电离室探测器,搭建了1/3规模实验样机,并对有机物加亮效应、背散射图像校正、复原等相关技术问题进行了仿真与实验研究。
Compton back-scattering imaging is more suitable for inspection of low density contrabands like explosives, drugs etc.According to this,a project was proposed for inspection of large objects using back-scattering imaging with detector array.A integrative gas champer was developed and a 1/3-scaled experimental system was built.Several technological problems were studied by simulations and experiments,including the highlighting effect of organic materials,image correction,image restoration.
