摘要

偏振x射线允许以纳米分辨率成像材料的双折射或二色性。为了从电子密度中分离出这些特性，需要一个极化分析仪或几个不同极化的测量（通常是两个或更多）。在这里，我们证明了触电学可以通过使用多模态分析将这些从单一偏振测量中解脱出来。当操纵入射偏振是不可能的或不够的时候，这种新方法提供了一种替代方法来获得样品的偏振分辨图像。2025年由美国物理学会出版

Magnetic X-Ray Imaging Using a Single Polarization and Multimodal Ptychography

Polarized x-rays allow for imaging birefringent or dichroic properties of materials with nanometric resolution. To disentangle these properties from the electronic density, either a polarization analyzer or several measurements with different polarizations (typically two or more) are needed. Here we demonstrate that ptychography can disentangle these from a single polarization measurement by using a multimodal analysis. This new method provides an alternative to obtain polarization-resolved images of a sample when manipulating the incident polarization is not possible or sufficient.
