微焦点X辐射密度解析成像方法及非线性校正

Micro-focus X-ray for density analytic imaging method and non-linear correction technique

提出了一种利用不同能量的Ｘ射线束所获得的图像来实现分离物体内部不同密度成分图像的方法，从本质上对这种算法进行了探讨，证明了这种算法的可行性；讨论了产生误差的原因，给出了对误差进行非线性校正的数学模型；并以两种成分的图像分离为例进行了实验，给出了实验结果。

In this paper, the authors brought up a method of using X-rays with varied energy spectra for density distributed imaging, the imaging algorithm, the sources of error, and the mathematical model of error correction were discussed. Finally, some experimental results were given. The results showed that the method was hopefully to be applied in practice.
