Abstract

Energy density approach as a modification of the coherent potential approximation was applied to analyze the influence of aging-caused changes in the fibrous tissue on its birefringence. The real fibrous tissue such as tendon was modeled by disordered array of partially oriented dielectric cylinders illuminated by a normally incident linearly polarized plane wave. The supraspinatus human tendon was taken as an object for theoretical modeling. The morphological features of the studied tissue were considered for a system of collagen fiber bundles embedded in a carbohydrate matrix. The latter one is a mixture of glycosaminoglycans and proteoglycans. Age-caused changes of the fibers and matrix influence on the spectral dependence of optical anisotropy spectrum.
