Abstract
The basic principles of laser refractography (LR), a new method for diagnostics of optically inhomogeneous media and flows, are described. This technology is based on the refraction of the structured laser radiation (SLR) in transparent inhomogeneity, digital registration and computer processing of the refraction pattern. The experimental setup allowed quantitative visualization of the inhomogeneous transparent media by using 2D or 3D-refractograms. The 3D-refractograms are used for diagnostics of the boundary layer near the hot or cold bodies in water are present.
