Abstract
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 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.

Bringing High-Resolution X-Ray Imaging to the Laboratory
Published 12 May 2021
Researchers have scaled down x-ray ptychography—a high-resolution imaging technique that used to require large, expensive facilities—for use in the lab.
