Quantum imaging with incoherently scattered light from a free-electron laser — •Raimund Schneider — Universität Erlangen-Nürnberg — Erlangen Graduate School in Advanced Optical Technologies

We report on a new method to reconstruct an unknown geometry of light sources using higher order spatial intensity correlations. Our imaging protocol allows the extraction of structural information from the light scattered by a source distribution even though the sources emit completely incoherently. The imaging method is of particular interest in the X-ray regime where coherence is easily lost, e.g., due to imperfect beam optics or incoherent scattering processes. We present experimental results of imaging a hexagonal source arrangement mimicking a benzene molecule. In the experiment the atoms are simulated by holes in a SiN membrane illuminated with the incoherent light scattered from a diffusor which itself is irradiated by the beam of the FLASH free electron laser at DESY, Hamburg.
