Fig. 7.

The effect of increased fibril diameters on light transmission. Secondary waves from the same collagen fibril distribution shown in Fig. 6. As before, primary incoming light is travelling from left to right (yellow arrow), with a wavelength of 500 nm. Collagen fibrils in transverse sections are represented by brown circles. 20% of the fibrils were selected at random and their diameter was doubled to 62 nm. The intensity of the secondary radiation arising from the fibrils is shown in blue. Backwards secondary radiation is evident in the figure (white arrows). Bar 500 nm.
