Abstract:		An experimental setup is developed to create, visually observe, and quantitatively investigate internal waves with a view to detecting the effects of alteration of the density distribution parameters in a diffuse layer of a salt-stratified liquid. Based on the application of a new laser refraction method combined with the direct shadowgraph technique, the density distribution parameters of the liquid layer are diagnosed during the course of propagation of solitary waves therein. The effect of pulsation of the thickness and density distribution of the layer during propagation of a soliton developing therein as a result of its initial stepwise perturbation is discovered experimentally.
