Non-coplanar 18-beam X-ray pinhole topographs for a silicon crystal were computer simulated by fast Fourier transforming the X-ray rocking amplitudes that were obtained by solving the n-beam (n = 18) Ewald–Laue dynamical theory (E-L&FFT method). They were in good agreement with the experimentally obtained images captured using synchrotron X-rays. From this result and further consideration based on it, it has been clarified that the X-ray diffraction intensities when n X-ray waves are simultaneously strong in the crystal can be computed for any n by using the E-L&FFT method.

实验获得和计算机模拟的硅晶体 X 射线非共面 18 束针孔形貌图

通过对 X 射线摇摆幅度进行快速傅里叶变换，对硅晶体的非共面 18 束 X 射线针孔形貌图进行了计算机模拟，该幅度是通过求解以下方程获得的：n-梁（n= 18) Ewald-Laue 动力学理论（EL&FFT 方法）。它们与使用同步加速器 X 射线捕获的实验图像非常一致。从该结果以及基于该结果的进一步考虑可知，当nX射线波在晶体中同时很强，可以计算出任何n采用EL&FFT方法。
