Experimental setup. The high-brightness X-ray beam produced by the liquid-metal-jet source is modulated by a static diffuser. The sample is mounted downstream on a translation stage for collection of reference images and sits on a rotation stage to perform the tomographic scan. The optical properties of the sample are encoded as distortions in the near-field speckle pattern produced by the diffuser and collected by a pixel array detector.
