基于双能量X射线透射技术的物质分类识别方法研究

X射线装置已被证实具有揭示物质的分子或原子特性的能力,这种特性对于探测违禁品是相当重要的。尽管X射线探测方法作为一种自动探测违禁品的有效手段已经开始商业化,然而大多数技术都还不是很成熟。研究了一种基于X射线透射技术的物质分类识别的更有效方法,物质按有效原子序数分成有机物、无机物和混合物,实验证明此方法是很有效的。

Study On Object Classification Base On Dual-Energy X-ray Transmission Technology

X-ray devices have demonstrated the ability to characterize a material at the molecular and atomic level. This ability is particularly important for detecting illicit materials. As X-ray detection methods which have increasingly been as an effective means for automatic detection of illicit materials now commercially available, most of these technologies are not yet mature. Object classification methods for using x-ray dual-energy transmission technologies more effectively was investigated., Investigation on object classification based on dual-energy x-ray transmission technology was made. R is a dimension relation to the effective atomic number. Classify the materials into organic 、inorganic and mixture by effective atomic number. It shows this method is very efficient by experimentation.
