Figure 2
Perspex spheres of 1.5 mm diameter enclosed in Kapton tape imaged at 30 keV, crystal bend = 0, at 15 mm PSW taken at (a) R2 = 0.25 m and (b) R2 = 1.48 m in hutch 2B and (c) R2 = 4.03 m and (d) R2 = 5.96 m in hutch 3B. The grey scale of the images has been normalized for display purposes, and are quantitatively comparable between sub-images. |
