台式X射线系统存在通量低、非相干性等局限，在显微成像、高精度测量等应用场景中面临巨大挑战．傅里叶变换关联成像（FGI）对相干性要求较低，据此原理发展出的空间相关多角度FGI能够有效提高成像效率，适用于台式X射线系统．然而该技术仍处于理论阶段，缺乏调制X射线并形成聚焦多光束的有效器件．为此，本文提出一种多光栅调制方法，将多个子光栅按特定方位排列对X射线进行调制．单个子光栅出射的X射线为空间相干光，各子光栅之间的X射线在样品位置非相干叠加，从而形成聚焦的多角度光束，有效提高台式X射线系统的通量利用率．本文对多光栅调制屏的调制原理进行阐述，通过数值仿真分析光栅尺寸、材质、厚度等参数的影响，并针对液态靶X射线源设计多光栅调制屏，并完成加工．本文的研究能够推动台式X射线系统在高分辨衍射成像中的应用．The desktop X-ray system has the limitations of low flux and poor coherence. It faces great challenges in application scenarios such as microscopic imaging and high-precision measurement. Fourier-transform ghost imaging (FGI) has low requirements on the coherence of the light source. Based on this principle, multi-angle FGI based on spatial correlation can effectively improve the imaging efficiency and is suitable for desktop X-ray systems. However, this technology is still in the theoretical stage, and there is a lack of effective devices to modulate Xrays and form focused multiple beams. To this end, a multi-grating modulation method is proposed in this paper. The partially coherent radiation of the X-ray source is modulated by arranging multiple subgratings in a specific direction. The X-ray emitted by a single sub-grating is spatially coherent light, and the X-rays between the sub-gratings are incoherently superimposed at the sample position to form a focused multiangle beam. This effectively improves the flux utilization of the desktop system. The modulation principle of multi-grating is described theoretically, and the key design parameters and their selection basis are clarified. Through numerical simulation, the modulation characteristics of partially coherent X-rays in the propagation process behind the modulation screen are systematically analyzed. By optimizing the parameters such as the size, material and thickness of the sub-grating, the influence of the sub-grating on the size, uniformity and diffraction efficiency of the focused spot is studied. The results show that when the sub-grating size matches the spatial coherence size of the X-ray source, the focusing effect of the beam can be significantly improved, and a smaller and uniform focal spot can be obtained. Based on the theoretical and simulation results, a gold multi-grating modulation screen is designed and fabricated for the liquid target X-ray source. Experimental validation of the simulation and theoretical predictions will be conducted once the experimental conditions are met. Once the experimental conditions are fulfilled, the focusing performance of the modulation screen will be further verified. The design and implementation of the modulation screen provide effective support and feasible path for multi-angle diffraction imaging and related applications in miniaturized X-ray systems.
