论文摘要
我们已经开发了一个3维相干衍射成像（CDI）算法，以检索放牧小角X射线散射（GISAXS）实验的样品衍射模式的相。该算法使用扭曲的波生近似（DWBA）而不是天生的近似（BA）来解释衍射模式，因为在这种情况下，从底物中存在反射的光束会导致衍射模式显着偏离对象的简单傅立叶变换。详细的计算机模拟表明该算法有效。计划进行实际实验验证。
We have developed a 3 dimensional Coherent Diffraction Imaging (CDI) algorithm to retrieve phases of diffraction patterns of samples in Grazing Incidence Small Angle X-ray Scattering (GISAXS) experiments. The algorithm interprets the diffraction patterns using the Distorted-Wave Born Approximation (DWBA) instead of the Born Approximation (BA), as in this case the existence of a reflected beam from the substrate causes the diffraction pattern to deviate significantly from the simple Fourier transform of the object. Detailed computer simulations show that the algorithm works. Verification with real experiments is planned.
