The schlieren method of studying density in the vicinity of a plane shock wave with consideration for the diffraction of a laser beam has been developed. An integral equation of the convolution type has been obtained for density, which is solved by means of Tikhonov's regularization method. The density restoration method proposed is employed for processing data obtained in the experiments with shock waves in the low temperature.plasma produced by an HF discharge in argon.
