Figure 3

(A and B) Scan lines on the two left human corneoscleral buttons used for microfocus WAXS. Solid line: coarse sampling (0.5 mm); broken line: fine sampling (0.05 mm). Shaded region denotes the limbus. (C) WAXS pattern from the limbal region of Cornea 1, showing the collagen intermolecular WAXS reflection centered at 1.6 nm. (D) Normalized x-ray scatter from fibrillar collagen as a function of rotation angle. Each of the 256 values in the distribution is extracted via a radial integration of the (background-subtracted) collagen WAXS peak. The clear region corresponds to preferentially aligned collagen, whereas the shaded region corresponds to isotropic collagen.
