Fig. 1: 3D rendering of a CPM image stack for specimens of technical applications; a) fiber-reinforced composite, b) multilayer foil. In c), the orientation of embedded fibers is extracted by mathematical post-processing; d) cross-section of the multilayer foil, where different layers and filler particles are recognizable. The imaging volume yields about 1 x 1 x 0.2 mm³
