Phys Rev Lett. 2008 Apr 18;100(15):155503. doi: 10.1103/PhysRevLett.100.155503. Epub 2008 Apr 17.

Abstract

We introduce a coherent diffractive imaging technique that utilizes multiple exposures with modifications to the phase profile of the transmitted wave front to compensate for the missing phase information. This is a single spot technique sensitive to both the transmission and phase shift through the sample. Along with the details of the method, we present results from the first proof of principle experiment. The experiment was performed with 6.0 keV x rays, in which an estimated spatial resolution of 200 nm was achieved.
