Abstract:
Light absorption is known to be one of possible mechanisms of light action on biological tissues. In any case, it always accompanies phototherapeutic irradiation of a living organism in practice. The objective of this paper is to quantitatively study the depth distributions of fluence rate absorbed by biotissue at several wavelengths of the visible to near-IR range, which can be used for phototherapeutic purposes. The investigations are made by the optical simulation method. The bases of them are the optical biotissue model [1] and the analytical procedures [2] for computing light transfer through biotissue.
