X 射线纤维衍射是研究 DNA 和合成聚合物等纤维材料结构的潜在强大技术。然而，只能记录旋转平均衍射图案，并且在没有深奥衍射理论知识的情况下很难正确解释它们。在这里，我们证明，原则上，纤维材料的非旋转平均 3D 结构可以从其纤维衍射图案中恢复。该方法是一个简单的解谜过程，在理想情况下，它不需要任何有关结构的先验知识，例如螺旋对称性。我们相信，所提出的方法有潜力将光纤衍射转变为 3D 成像技术，并将在生命和材料科学的广泛领域发挥作用。
X-ray fiber diffraction is potentially a powerful technique to study the structure of fibrous materials, such as DNA and synthetic polymers. However, only rotationally averaged diffraction patterns can be recorded and it is difficult to correctly interpret them without the knowledge of esoteric diffraction theories. Here we demonstrate that, in principle, the non-rotationally averaged 3D structure of a fibrous material can be restored from its fiber diffraction pattern. The method is a simple puzzle-solving process and in ideal cases it does not require any prior knowledge about the structure, such as helical symmetry. We believe that the proposed method has a potential to transform the fiber diffraction to a 3D imaging technique, and will be useful for a wide field of life and materials sciences.
