From: Femtosecond multimodal imaging with a laser-driven X-ray source
a An absorbing mask splits the X-ray beam into beamlets which are imaged with a pixelated detector. b the presence of the sample between the mask and the detector changes the beamlets’ shape. c, d Cropped detail (2.7 × 3.1 mm) of transmission images of the mask used in this experiment without (c) and with (d) sample (detail of a leaf margin). e line profiles from c and d of the beamlets with (solid red line) and without sample (dashed blue line). See Supplementary Note 1 Fig. S1 for the full-size raw images.
