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.

具有相干照明的混合实空间和倒易空间全场成像

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实空间图像来指导相位检索。开发了一种计算算法以在迭代阶段检索过程中利用这种先验知识作为实空间约束。进行了数值模拟和概念验证实验，证明了我们的方法能够重建传统定相算法无法实现的高分辨率细节。使用本方法，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。
