通过分数阶傅里叶变换解释 X 射线相干衍射

X-ray Coherent diffraction interpreted through the fractional Fourier transform

David Le Bolloc'h, Jean-Francois Sadoc

AI总结:

该研究提出用分数阶傅里叶变换统一描述相干 X 射线从菲涅耳到夫琅禾费区的衍射,并结合惠更斯-菲涅耳理论引入广义不确定性原理。

摘要:

本文利用 Fractionnal Fourier transform(分数阶傅里叶变换)处理相干 X 射线束的衍射。该变换使我们能够处理从 Fresnel(菲涅耳)区到 Fraunhofer(夫琅禾费)区的相干衍射实验。文中首先讨论了与 Huygens-Fresnel(惠更斯-菲涅耳)理论的类比,并引入了广义不确定性原理。

英文摘要:

Diffraction of coherent x-ray beams is treated through the Fractionnal Fourier transform. The transformation allow us to deal with coherent diffraction experiments from the Fresnel to the Fraunhofer regime. The analogy with the Huygens-Fresnel theory is first discussed and a generalized uncertainty principle is introduced.
