Figure 7
Phase reconstructions of the crossed carbon fibre sample via grating interferometry in a projection microscope (a) with mT = 11/16 and via PBPCI (b). The scale bar indicates 10 µm length in both panels. Panels (c) and (d) show section profiles along the line segments indicated in (a) and (b), respectively (green curves). The expected profile for carbon fibres with a diameter of 7.2 µm and 6.4 µm is shown for comparison (blue dash-dotted curve). Note, that the expected profile plot was adjusted to the baseline of the reconstructions. |
