Annotation: We show the block diagram of video registrator meant for studying of wave dynamics of plasma jets at a spraying of powder coatings, as well as the principle of its work is stated in the paper. Processing of image stream has allowed to define the distributions of particle velocities and of particle density in various cross-sections of a plasma stream when spraying powder coatings on the machine parts.

Keywords: image processing, the distributions of particle velocities and of particle density
