associated with various biophysical, biochemical, and physiological processes, and
can be computed for lasers with other parameters; the quantitative estimates obtained
in this study can be applied for processing and interpreting experimental data.
We have described the mathematical model for calculating the optical characteristics and for analyzing the biophysical processes of propagation of light in a multilayer
biotissue in the case of the interaction with noncoagulating laser radiation. The model
was implemented in the form of a software package, which makes it possible to vary
automatically the composition of biological objects, their electrophysical parameters,
characteristic thicknesses of layers, as well as characteristic sizes of various biological structures under investigation on the same setup for recording the dependence
between these parameters. This makes the software developed here an effective and
convenient tool for investigations in biomedical optics.
