Abstract :
Optical absorption characteristics of multicomponent biological tissues are studied and compared for two cases, namely, for homogeneous and discrete localization of the absorbers. The known calculation procedure is essentially simplified by replacing cylindrical blood vessels with parallelepipedal ones to enable us to reduce the problem to simple single integration. The comparison of the two computation methods shows their excellent agreement. The effects of localized absorbers are discussed as applied to light and heat transfer through biological tissues. The proposed procedure is useful to study optical characteristics of a composite medium containing absorbing, large enough inclusions of any shapes.
