Diffraction imaging results of the bifocal PS at 8.39 keV

The dataset includes diffraction imaging results of two focal lengths (f=158.23 mm, f=224.01 mm) of a dual focal photon sieve. The experiment adopts an equal-size imaging method, with the object distance set to twice the corresponding focal length, and the image distance also being twice the corresponding focal length. For f=224.01 mm, at the same object distance, the experiment showed the light intensity distribution of the photon sieve diffraction imaging from different positions at intervals of 25 mm. CCD resolution is 13 μ M.

本数据集包含双焦点光子筛（dual focal photon sieve）在两种焦距（f=158.23 mm、f=224.01 mm）下的衍射成像结果。实验采用等尺寸成像方案，物距设定为对应焦距的两倍，像距亦为对应焦距的两倍。针对焦距f=224.01 mm的工况，在相同物距条件下，实验获取了光子筛衍射成像在以25 mm为间隔的不同位置处的光强分布。电荷耦合器件（Charge-Coupled Device，CCD）的分辨率为13 μm。
