Abstract :
A couple camera-computer provides a possibility of simple characterization and monitoring of plasma jets. This paper demonstrates another way of characterization of plasma flow structure by statistical processing of plasma jet images. The processing is based on an analysis of variations of local brightness in a sequence of images recorded by fast shutter camera. Resulting pictures show space distribution of plasma jet brightness fluctuations.
