X-ray ghost imaging using individual synchrotron pulses

Ghost imaging is an indirect method in which most of the X-rays used for the experiment never actually interact with the sample. The first demonstration of X-ray ghost imaging has been carried out at beamline ID19. The method uses two copies of the same speckled beam and the image is retrieved indirectly by correlating the two measured signals. This experiment could lead to the development of low-dose medical X-ray diagnostics and diffraction-imaging at free electron lasers.
