Abstract

Coherent diffraction imaging (CDI), a type of lensless imaging method, relies on the use of light source with high-degree coherence to compute highly resolved complex-valued objects. The coherence of light source consists of temporal coherence and spatial coherence. In practice, it is difficult to obtain a fully coherent source. Spatial decoherence can be generated in the following three scenarios: no synchronization mechanism for the whole radiation source, a finite (non-zero) point spread function of the detector, and the sample variation within exposure time. Partial temporal coherence means that the beam is not quasi-monochromatic, behaving as the energy spread of the illumination. The consequence of reduced degree of temporal and/or spatial coherence in CDI is the decrease of visibility in the measured diffraction intensity. A fundamental assumption of CDI is the full temporal and spatial coherence, and even a relatively small deviation from full coherence can prevent the phase retrieval algorithm from converging accurately. It is necessary to break the barrier of limited coherence by improving the experimental setups directly or optimizing the phase retrieval algorithms to mitigate decoherence. Based on the Wolf’s model of coherence-mode of light and the framework of CDI using partially coherent light proposed by Nugent et al., various methods have been proposed to solve the problems induced by low coherence. Those methods generally experience a similar development process, that is, from the requirement for measuring the spatial (coherent length or complex coherent factor) or temporal (spectrum distribution) coherence properties to without the need for such priori knowledge. Here in this work, the principles of partial coherent CDI, and the major progress of CDI with partial spatial- and temporal-coherent light are reviewed.

图 8 衍射图样数值单色化的原理图^[105]. 传统的CDI假设照明光源是单色的. 对于阿秒宽带光源, 衍射图样是所有波长所对应的单色衍射图样的加权叠加. 这些单色的衍射图样可以认为只有几何缩放的差别. 这种缩放是数值可逆的, 由矩阵C来表示该缩放矩阵. 确定了C之后, 就可以通过求解矩阵向量问题b = Cm从宽带光衍射图样b中提取出单色化的衍射图样m (图中右下部分所示为对应于一维衍射图样的简化情形). 然后就能直接将m代入到传统的相位恢复算法中重构出样品的复振幅信息. ℓ是复色光所包含的离散化光波的波长个数

Figure 8. Principle of the numerical monochromatization^[105]. Conventional CDI assumes a monochromatic source. In the case of an attosecond broadband source, the diffraction pattern is the incoherent, spectrally weighted sum of the monochromatic diffraction patterns corresponding to all wavelengths presents in the sources. These monochromatic patterns are identical except for a geometric scaling. In the presented method this scaling is numerically inverted, and the scaling matrix is denoted by matrix C. The monochromatization method consists in the inversion of the matrix-vector problem b = Cm in order to retrieve the monochromatic diffraction pattern m from the broadband measurement b (The lower right part of the figure shows the simplified case for 1D diffraction pattern). Then m can be directly put into the conventional phase retrieval algorithm. ℓ is the index that corresponds to the spectral discretization.
