Figure 4.
(a – d) are the amide III and sugar anisotropy profiles of the perpendicular sections at the tissue depths of 18.75, 100, 256.25 and 525 μm respectively. (e – h) are the amide III and sugar anisotropy profiles of the parallel sections at the depths of 18, 102, 258, and 528 μm respectively. The lines on these profiles are the fittings based on Eq. (1). Although each anisotropy profile on this figure has a different vertical scale, all profiles have the same difference in the range infrared absorption value of 0.06.
