A mathematical model for propagation of visible and infrared optical radiation and submillimeter wavelength terahertz radiation through different media, as well as interaction of the aforementioned types of radiation with matter is proposed. The model is adapted to the problems of remote sensing and imaging of biological objects behind the opaque barriers. Questions concerning the recovery of surface relief and type of the tissue being irradiated are discussed. The model has been verified during the series of experimental research with the use of phantoms (substitutes) of the biological objects. Calculation results can be applied for personal identification by face recognition under the individual means of protection [1] or for inspection of injured tissue under non-metal bandages and dressings.
