Femtosecond multimodal imaging 

Laser-driven x-ray sources can provide incredibly short x-ray pulses. This experiment combined their use with a single-mask implementation of our edge-illumination technology (“beam tracking”, see “Previous Advances”), which enables the simultaneous retrieval of attenuation, phase and dark-field images from a single frame. As a result, all three images were obtained from a single shot of 22 fs duration, which open new possibilities for e.g. pump-probe experiments.
