Fibrous tissue optical properties control

The changeable scattering properties of fibrous tissue like the human sclera were studied in vitro. The collimated light transmittance, photon-correlation, and polarization measurements were done. The optical characteristics of fibrous tissue were controlled using various osmotically active solutions including glucose. It was shown that refractive indices matching of collagen fibrils and base material of fibrous tissue is responsible for tissue optical enlightening and coherent beam transmittance.
