Test object and representative MIR2 results for a single FOV. (a) Front and back views of the test object, consisting of two orthogonally oriented PMMA step-wedges (step-wedge 1 and 2) and a 20-layer paper step-wedge (stack). The dashed red box indicates the FOV analyzed in panel (b). (b) Left: extracted rocking curves from the calibration region for the reference and object datasets after angular calibration. Right: MIR2 contrast maps from the indicated FOV, including refraction, USAXS, transmission, and radiograph. The displayed previews are intensity-scaled for visualization, whereas exported TIFF files preserve the original floating-point values.
