论文摘要
暗场X射线显微镜(DFXM)是一种基于衍射的同步子成像技术,能够在大部分扩展的晶体样品中成像缺陷。我们使用动力学高高键蛋白方程(TTE)和波前传播的数值整合在这种显微镜中介绍了图像形成的数值模拟。我们通过将模拟图像与来自近乎完美的单晶钻石的实验数据进行比较来验证我们的方法,该图像包含照明体积中的单个堆叠故障缺陷。
Dark-Field X-ray Microscopy (DFXM) is a diffraction-based synchrotron imaging techique capable of imaging defects in the bulk of extended crystalline samples. We present numerical simulations of image-formation in such a microscope using numerical integration of the dynamical Takagi-Taupin Equations (TTE) and wave front propagation. We validate our approach by comparing simulated images to experimental data from a near-perfect single crystal of diamond containing a single stacking fault defect in the illuminated volume.
