Figure 3
XA images (OD contrast) of natural spheroidal graphite at 285.7 eV, measured at a wide range of polarization angles, θ = 0°–180° for the LH and LV modes; the FOV is 9 µm × 9 µm with a pixel size of 90 nm. The red and blue arrows indicate the X-ray polarization directions of LH and LV, respectively. |
