چکیده انگلیسی
In an optically homogeneous medium (a medium in which the refractive index is the same in any point) light spreads rectilinearly without being refracted. However, the refractive index can be changed, its gradient can be created as a result of making inhomogeneity. Such inhomogeneity can be made by diffusion of liquids or their heating, cooling, and so on. One actual and promising method of researching optically inhomogeneous media is the method of the laser refractography. It is based on the phenomenon of refraction of structured laser radiation in optically inhomogeneous media and registration of its form deviations with the digital camera. Two types of optical inhomogeneities are researched in this work: a diffusion layer of liquids and temperature fields near heated or cooled objects. It was considered conditions for the occurrence of caustics in longitudinal probing of optical stratified inhomogeneous media by plane and cylindrical laser beams in this paper. Experimental setup for 3D-visualization of laser beams' refraction was shown.
