The invention provides an X-ray backscattering imaging safety inspection device based on lobster eye optical elements. X-ray focusing elements and X-ray compton scattering technology are combined, planar microporous optical elements are utilized to effectively focus X ray light beam emergent from an X ray light source, spherical microporous optical elements are utilized to realize compton backscattering hard X-ray data collection within a whole target view field through an array symmetrical structure, dangerous goods can be scanned rapidly and real-time image display can be achieved. Under the premise of high efficiency and safety, the device provided by the invention can effectively reduce the detection time and improve the image resolution. 本发明提供种基于龙虾眼光学元件X射线背散射成像安检装置，采用X射线聚焦元件和X射线康普顿散射技术相结合，利用平面微孔光学元件有效聚焦X射线光源出射X射线光束并利用球面微孔光学元件通过阵列对称式结构实现对整个目标视野内进行康普顿背散射硬X射线数据收集，可快速扫描到危险物品并实时图像显示。在高效安全的前提下，本发明可有效降低检测时间，提高图像分辨率。
