提出了一种基于合成衍射图的定量对比度增强成像概念，用于位相恢复。利用合成衍射图的原始位相恢复算法可以恢复虚拟样品，合成衍射图是由有或没有原始弱相样品的衍射图合成的。与原始试件相比，虚拟试件在结构不变的情况下，幅值和相位对比度均有明显提高。从理论上和定量上确定了虚拟试件与实际试件之间的换算关系。分别用扩展层析迭代引擎和相干调制成像的仿真和实际实验验证了该方法的有效性，结果与理论分析的结论一致。该概念为现有的不同光源的相位恢复算法提供了一种简单、通用、实用的成像增强技术。
A quantitative contrast enhancement imaging concept for phase retrieval based on the synthetic diffraction patterns was proposed. A virtual specimen could be retrieved by original phase retrieval algorithms using synthetic diffraction patterns which are compounded from the diffraction patterns both with and without original weak phase specimen. Compared to the original specimen, the amplitude and phase contrast of the virtual specimen were distinctly enhanced while the structures were not changed. The conversion relationships between the virtual and actual specimen were theoretically and quantitatively determined. The validity was demonstrated by simulations and practical experiments with extended ptychographic iterative engine and coherent modulation imaging respectively, and the results agree with the conclusions of the theoretical analysis. The proposed concept provides a simple, universal and practical imaging enhancement technique for existing phase retrieval algorithms with different light sources.
