Schematic illustration (a) and photograph (b) of the IL-PCI experimental setup at BL13W1 at the Shanghai Synchrotron Radiation Facility (SSRF). Here, the quasi-coherent parallel X-ray beams are generated by the 3.5 GeV electron storage ring and are monochromated by a double-crystal monochromator with Si(111) crystals, and then illuminate the sample on the rotation stage. When the transmitted beams propagate from the sample, the density variation causes phase shifts. Because of Fresnel diffraction, the phase shifts are transformed into detectable intensity variations and subsequently recorded by a detector set at a specific distance. Finally, the projection image of IL-PCI is displayed in the image acquisition system. For tomographic scans, the sample can be rotated from 0° to 180° to collect the projection images from various views.
