Figure 1
Schematic depiction of the IL-PCI setup at BL13W at Shanghai Synchrotron Radiation Facility (SSRF). Here, a white beam was monochromated by a double-crystal monochromator, and the sample was illuminated on the rotation platform. When the transmitted beam passed through the sample, the density variation resulted in phase shifts. Finally, a projection image, containing a mix of phase shifts and attenuation coefficients, could be recorded by the detector in the image plane and subsequently displayed in the image acquisition system. For tomographic scans, the sample can be rotated from 0° to 180° to acquire the projection images from various views.
