Refraction of the Flat Optical Beam in a Transparent Heterogeneous Environments


Presents a method of visualization and laser diagnostics of optically inhomogeneous media based on the phenomenon of refraction of the structured laser radiation (SLR). The described method of studies of the diffusion layer of the optical refractography method. Experimental setup for digital recording refractive pattern (refractograms). Shown for examples application of methods of the laser refractography thermal processes.
