| Abstract: |
The work is devoted to investigation of heat and mass transfer processes by laser refractography method which based on phenomena of refraction of structured laser radiation (SLR) probing an optical inhomogeneous medium and also digital registration and computer processing of receiving images (refractograms). When SLR propagates in optical inhomogeneous medium the caustics may appear, whose coordinates can be determined with high accuracy. It gives additional possibilities for reverse problem solving on reconstruction of physical properties of media which cause to inhomogeneity in refractive index. The conditions of caustics appearing are considered in case of longitudinal probing of stratified media by plane and cylindrical laser beams. The results of computer modeling of 3D-refractograms of SLR propagation in diffusive liquid layer and in temperature fields appearing near heated and cooled objects are represented. Comparison of experimental and calculated refractograms are given. |
