Photographs of the experimental setup. The X-ray beam was focused by a set of beryllium CRL lenses (a) and a phase plate with horizontal and vertical degrees of freedom was placed downstream of the CRL optics. The grating/speckle phase modulators were mounted on a motorized positioner with long travel range along the optical axis (b). Two indirect X-ray detectors (c) with YAG scintillating screens were placed further downstream at approximately 2 m distance from the focus, and the compact moiré interferometer was mounted as the last part of the setup (d).
