论文摘要
我们提出了一种新颖的衍射成像方法，该方法利用低分辨率的真实空间图像来指导相位检索。开发了一种计算算法来利用迭代阶段检索过程中的真实空间约束之类的先验知识。进行了数值模拟和概念验证实验，证明了我们方法重建高分辨率细节的能力，这些细节与传统的相位相位算法无法访问。使用当前方法，我们为下一代X射线光源的相干成像实验制定了概念设计。
We present a novel diffractive imaging method that harnesses a low-resolution real-space image to guide the phase retrieval. A computational algorithm is developed to utilize such prior knowledge as a real-space constraint in the iterative phase retrieval procedure. Numerical simulations and proof-of-concept experiments are carried out, demonstrating our method's capability of reconstructing high-resolution details that are otherwise inaccessible with traditional phasing algorithms. With the present method, we formulate a conceptual design for the coherent imaging experiments at a next-generation X-ray light source.
