Abstract

A mathematical model of the output signals of an X-ray sandwich detector is presented. Based on this model, two mathematical models of the radiation transparency of the test object for a sandwich radiation detector have been developed. These models are the basis for a theoretical assessment of the accuracy of recognizing materials using the corresponding implementation scheme of the dual-energy method. The fundamental difference between the developed models is that one of them does and the other does not take into account statistical dependence between the output signals of the sandwich detector. Recommendations on the preference for using each of these models are given.

使用夹心X射线辐射探测器时测试对象的辐射透明度的数学模型

摘要

提出了X射线夹心检测器输出信号的数学模型。基于该模型，已经开发出两个用于夹层辐射探测器的测试对象的辐射透明度的数学模型。这些模型是使用双能量方法的相应实现方案对材料识别的准确性进行理论评估的基础。所开发的模型之间的根本区别在于，其中一个模型确实做到了，而另一个模型没有考虑到三明治检测器输出信号之间的统计依赖性。给出了关于使用每种模型的偏好的建议。
