Abstract
Over the past few years, results from the phase contrast imaging and tomography (PCIT) beamline at the Singapore Synchrotron Light Source (SSLS) have shown that high resolution (about 1 μm) 2-dimensional (2D) and 3-dimensional (3D) can be achieved in spite of the large emittance of the Helios 2 storage ring. Using white radiation the photon flux is high enough to perform real time radiology (100 ms per frame) at high lateral resolution as well as high-speed 2D imaging and 3D tomography. Refractive edge enhancement was also observed. PCIT is mostly used for materials and process characterization. © 2007 Elsevier B.V. All rights reserved.
