Optical properties of biological tissues evaluation with a hybrid goniometer and integrating-sphere technique and Monte Carlo mathematical modelling

Abstract

Abstract A novel technique for measurements of optical properties of biological tissue samples is proposed. The scattered radiation pattern of the irradiated tissue was measured experimentally by changing the distance from the sample to the inlet of the integrating sphere. A Monte Carlo method was used for simulations of the radiation propagation in the sample. The optical properties of the aloe arborescens were determined via comparison of the simulation results to the experimentally measured angular dependence of the light power scattered and transmitted through the sample.
