Query: Experimental x-ray ghost imaging   We report an experimental proof of principle for ghost imaging in the hard
x-ray energy range. We used a synchrotron x-ray beam that was split using a
thin crystal in Laue diffraction geometry. With an ultra-fast imaging camera,
we were able to image x-rays generated by isolated electron bunches. At this
time scale, the shot noise of the synchrotron emission process is measurable as
speckles, leading to speckle correlation between the two beams. The integrated
transmitted intensity from a sample located in the first beam was correlated
with the spatially resolved intensity measured on the second, empty, beam to
retrieve the shadow of the sample. The demonstration of ghost imaging with hard
x-rays may open the way to protocols to reduce radiation damage in medical
imaging and in non-destructive structural characterization using Free Electron
Lasers.
