Free-Electron Lasers provide coherent highly intense and short pulses which make it possible for the first time to analyze the morphology of non-periodic or non-crystallizable nanoparticles by elastic light scattering. As the phase information is lost due to the imaging process it has to be retrieved to extract full structural information. In former approaches sophisticated techniques were necessary in order to regain the phase. For solid targets holographic methods were applied successfully which retrieve the phase information in a much faster and less expensive way. We recently developed single-shot in-flight-holography using pulses from the Linac Coherent Light Source (LCLS) to image undistorted viruses in water droplets using the scattered light from xenon nanoclusters as a reference wave. First results and resolution limits through experimental constraints will be discussed.
