摘要：
我们提出了一种新颖的轴向投影衍射成像（AP-CDI）技术，旨在克服传统方法的关键通量瓶颈。通过将二维扫描替换为简单的单轴扫描，我们的方法将所需的衍射图案数量减少了一个数量级，同时保持高保真的重建。我们已通过实验验证了这一概念，成功实现了样品的光谱成像和照明的定量波前表征，从而准确量化了宽带光源的色差。这种能力使AP-CDI成为一种高效且多功能的实时多模式成像工具，具有在超快科学、材料表征和活细胞生物成像中的即时应用潜力。
英文摘要：
We present a novel axial ptychographic coherent diffractive imaging (AP-CDI) technique designed to overcome the critical throughput bottleneck of conventional methods. By replacing the 2D raster scan with a simple 1D axial scan, our approach reduces the number of required diffraction patterns by approximately an order of magnitude while maintaining high-fidelity reconstruction. We have experimentally validated this concept, successfully performing simultaneous spectroscopic imaging of a sample and quantitative wavefront characterization of the illumination, thereby accurately quantifying the chromatic aberration of a broadband field. This capability establishes AP-CDI as a highly efficient and versatile tool for real-time, multi-modal imaging, with immediate potential in ultrafast science, material characterization, and live-cell bio-imaging.
