一种基于双能X射线与前向散射的爆炸物检测方法

A new method of explosive detection based on dual-energy X-ray technology and forward-scattering

本文简要介绍了爆炸物检测领域的各种现行方法,指出了它们的优缺点。与它们相比,本文探讨的新方法具有一系列独特的优点。本文作者提出了一种新颖的爆炸物检测方法,即(双能 X 射线)+(前向散射法)。使用双能 X 射线法可以得到被检测物质的有效原子序数信息,利用 X 射线的前向散射可以得到被检测物质的密度信息,而有效原子序数和密度这两个特征量的组合就可以有效地表征爆炸物的存在。

Based on dual-energy X-ray technology combined with forward-scattering, a brand new explosive detection method is presented. Dual-energy technology can give the information on the effective atomic number (Zeff) of an irradiated component, while the intensity of the forward scattered photons can reveal the density information according to our research. Therefore, the existence of the explosive can be effectively identified by combining these two characteristic quantities. Compared with the earlier inspection approaches, the new one has a series of particular advantages, such as high detection rate, low false alarm rate, automatic alarm and so forth. The project is ongoing.
