Structured light has sparked interest by introducing a parameter to adjust light–matter interactions in photonics applications. While phase structures applied to their wavefronts enable functional imaging probes, their application in X-ray microscopy has been limited due to their complex configuration. Here, we present X-ray vortex beam ptychography using an off-axis spiral zone plate, showcasing quantitative nanoscale imaging with straightforward manipulation of the phase structure. The simple experimental setup enhances adaptability to most light sources. This coherent X-ray microscopy, capable of resolving nontrivial topological states with additional phase structures of light, is poised to advance photonics research by leveraging topological features.

离轴 X 射线涡旋束叠层成像

结构光通过引入一个参数来调整光子学应用中的光与物质相互作用，引起了人们的兴趣。虽然应用于波前的相位结构可实现功能性成像探头，但由于其复杂的配置，它们在 X 射线显微镜中的应用受到限制。在这里，我们展示了使用离轴螺旋波带板的 X 射线涡旋束叠层成像技术，展示了通过直接操纵相结构进行定量纳米级成像。简单的实验设置增强了对大多数光源的适应性。这种相干 X 射线显微镜能够解析具有附加光相结构的非平凡拓扑态，有望通过利用拓扑特征来推进光子学研究。
