    • PROBLEM TO BE SOLVED: To provide an object imaging system and method using a backscattering radiation.SOLUTION: An imaging system 5 includes a radiation source 10 which irradiates an object 22, and the radiation source can rotate around the object. The imaging system 5 also includes a detector 15 which detects backscattering radiation from the object 22. The detector 15 is arranged at substantially the same side of the object 22 such that a light source and the detector can rotate and move with the object as a center. The detector 15 can be divided into a plurality of detector segments such that each segment has the single line of sight of projection passing through the object, and that the radiation can be detected only by following the line of sight. The limited line of sight enables each detection segment to separate the desired components of the backscattering radiation. The radiation source 10 and the detector 15 collect a plurality of images of the object at different rotation angles, and independently move about the object. The plurality of images can be used for generating the three-dimensional restoration of the object.
    • 要解决的问题:提供使用后向散射辐射的物体成像系统和方法。解决方案:成像系统5包括照射物体22的辐射源10,并且辐射源可围绕物体旋转。 成像系统5还包括检测器15,其检测来自物体22的反向散射辐射。检测器15布置在物体22的基本相同的一侧,使得光源和检测器可以以物体为中心旋转和移动 。 检测器15可以被分成多个检测器段,使得每个区段具有通过物体的投影的单一视线,并且仅通过跟踪视线来检测辐射。 有限的视线使得每个检测段能够分离反向散射辐射的期望分量。 辐射源10和检测器15以不同的旋转角收集物体的多个图像,并且独立地围绕物体移动。 多个图像可以用于生成对象的三维恢复。
