Abstract

A computer model of blood vessel heating by pulse laser irradiation incident on the upper skin layer (epidermis) is suggested. The model is a multilayered half-infinite structure. The depths, optical (absorption and scattering), mechanical and thermal-optical properties of layers are in agreement with the real properties of epidermis and dermis of skin. The exterior of model object (epidermis) is illuminated by light beam of cylindrical form with homogeneous intensity distribution along the cross section. The blood vessel, situated in dermis, is simulated by infinite circular cylinder. Calculations of the dynamics of temperature field inside blood vessel taking into account an inhomogeneous distribution of volumetric heat release within it under the action of pulse laser irradiation of skin were made.
