摘要：
The base error of the optophysical method of measuring the parameters of an air shock wave formed as the result of the explosion of an explosive charge is estimated. With the use of reference data, the process of measuring the parameters of an air shock wave by the black box method was simulated. Values were obtained for the mean standard deviation of the result of measuring the overpressure of air in the air shock wave front for various conditions (spatial resolution, frame frequency) of the video recording of the process of exploding explosive charges of various mass.
