Sažetak
Manufacturing significance of optical properties of paper motivated us to construct a theoretical approach which could be used to determine the reflection and dispersion of light from paper surface. We introduced a method based on the Monte Carlo model of light scattering in paper for better understanding the origin of optical screen values gain and to provide a more realistic description of the medium in which light scattering occurs. The Monte Carlo method was used as a frame within which we were able to describe the diffuse scattering of light which suffers multiple subsurface reflections. Our simulation provides a flexible and at the same time rigorous approach to the transport of light in a medium such as paper. We numerically investigated the effects of the modeled surface on the optical properties of paper throughout subsurface light scattering.
