由衍射限制存储环提供的相干通量的预期增加将使光刻达到前所未有的吞吐量，同时保持其固有的定量性质和计量的多功能性。X射线层析成像是一种扫描相干衍射成像技术，有望以剂量受限的分辨率和灵敏度成像。如果可预见的相干通量数量级的增加可以与其他技术和分析进步相匹配，则层析成像可能会接近与全场方法相似的成像速度，同时保留其固有的定量性质和计量的多功能性。除了高通量的承诺外，三维光谱应用变得可行，通过时间分辨成像或仔细描述退相干效应来测量样品动力学也是可行的。
The foreseen increase in coherent flux provided by diffraction-limited storage rings will allow ptychography to reach unprecedented throughput while retaining its inherently quantitative nature and metrological versatility. X-ray ptychography, a scanning coherent diffractive imaging technique, holds promise for imaging with dose-limited resolution and sensitivity. If the foreseen increase of coherent flux by orders of magnitude can be matched by additional technological and analytical advances, ptychography may approach imaging speeds familiar from full-field methods while retaining its inherently quantitative nature and metrological versatility. Beyond promises of high throughput, spectroscopic applications in three dimensions become feasible, as do measurements of sample dynamics through time-resolved imaging or careful characterization of decoherence effects.
