This experiment demonstrated the successful application of X-ray ptychography in a small-scale laboratory setting, showcasing the potential for high-resolution phase contrast imaging to be performed at small-scale sources worldwide.
X-ray ptychography has revolutionized nanoscale phase contrast imaging at large-scale synchrotron sources in recent years. We present here the first successful demonstration of the technique in a small-scale laboratory setting. An experiment was conducted with a liquid metal jet x-ray source and a single photon-counting detector with a high spectral resolution. The experiment used a spot size of 5 mu m to produce a ptychographic phase image of a Siemens star test pattern with a submicron spatial resolution. The result and methodology presented show how high-resolution phase contrast imaging can now be performed at small-scale laboratory sources worldwide.
