X-ray phase-contrast imaging enables the retrieval of the electron-density distribution in a sample probed by X-rays. Propagation-based and grating-based X-ray phase-contrast imaging are full-field imaging techniques by which the electron-density distribution can be retrieved with a single acquisition. This, i.e. single-shot imaging, is essential for the acquisition of the processes and dynamics of laser-shocked plasmas. In this contribution both approaches are introduced and their application as a diagnostics tool for electron-density distributions of laser-induced plasmas is addressed. In particular, their implementation and resolving power at pump-probe experiments with an X-ray backlighter are presented.
