Solving the inverse problem of determining the optical characteristics of light-scattering materials in the visible and IR regions on the basis of two-parameter, two-flux scattering theory

Using chalcogenide glasses as an example, it is shown that a two-parameter, two-flux theory of light scattering can be used to describe the optical pr operties of a light-scattering medium in the IR region when the absorption coefficients are moderate (no greater than 0.2-0.3). The characteristics of an elementary volume of chalcogenide glass are calculated in the region of its short-wave length transmission limit, and the variations of the reflec tion and transmission coefficients as the thickness of a plane-parallel pol ished sample varies are predicted.
