Optical properties of composite systems based on anisotropic fibers with axisymmetric stacking

Simulation of optical properties of composite systems in the form of bundles consisting of anisotropic fibers with axisymmetric stacking is carried out in the ray-optics approximation. It is shown that such composite systems observed by the interference-polarization method for the case of crossed Nicol prisms produce figures in the form of a system of concentric light and dark rings, in the center of which there is a dark cross. The results of simulations applied to microsections of the human tooth taking into account the numerical values of the constituent components of the dentin (the sizes and optical properties of the dentinal tubules and of the matrix, etc.) are compared with the experiment. A good qualitative agreement between the calculation and the experiment for the observed patterns is found in the cases of some samples (molar and premolar).
