In this article the authors propose methods of quantitative estimation of the processes’ gas-dynamic parameters in gaseous media, based on the results of optical recording. The basis of this technique is a well-known dependence of a directly proportional relationship between the brightness of the image and the second derivative of gas flow density with respect to the coordinates. Comparison of experimental and calculated data showed that the developed method allowed to perform a quantitative estimation of the processes’ gas-dynamic parameters in gaseous medium correctly. It leads to a significant increase in the number of possibilities of optical registration of aero-physical and ballistic experiments and makes these experiments cheaper and simpler.
