MTF obtained via the slanted-edge approach utilizing the GaAs [110] wafer along the cleavage plane inclined for 5° along the vertical axis of the detector. The cleaved edge was imaged with single harmonic X-ray illumination at 18 keV utilizing two detector arrangements; namely, with the 10× NUV-sensitive and visible-light-sensitive M Plan Apo microscopes combined with both LYSO:Ce and LuAG:Ce scintillator single crystals of 250 µm thickness. |
