Effect of transparent layer on light propagation in optical skin phantoms: a Monte Carlo simulation study

In the field of Biomedical Optics, understanding how transparent layers affect light propagation in tissue is crucial for optimizing therapeutic and diagnostic applications. We employed Monte Carlo simulation to analyze changes in light behavior when introducing a transparent layer onto a multilayer optical skin phantom. Our study revealed that adding a transparent layer alters the illuminated volume, with changes influenced by the refractive index and thickness of the layer. This insight emphasizes the significance of both composition and thickness of transparent materials in influencing light propagation within the skin model. Such knowledge is fundamental for improving light-based therapies and diagnostics in Biomedical Optics.
