WebOptical scattering originates from light interaction with biological structures ranging from cell membranes to whole cells. The size of this scattereres varies from 10 nm to 10 microns. These scattereres are distributed randomly in biological tissue; photons usually encounter multiple scattering events. WebOptical properties of the dermis are modelled using the Kubelka-Munk approach, and calculations of scattering and absorption coefficients are presented. This simple approach allows estimates of the penetration of radiation in vivo using noninvasive measurements of cutaneous spectral remittance (diffuse reflectance).
WebJun 24, 2024 · An accurate knowledge of tissue optical properties (absorption coefficients, μ a, and reduced scattering coefficients, μ s ’) is critical for precise modeling of light propagation in biological tissue, essential for developing diagnostic and therapeutic optical techniques that utilize diffusive photons.
