The structure and stability of a thermal plasma jet were studied on the basis of statistical analysis of images of a plasma jet taken by a fast shutter camera. The space distribution of the mean value and the standard deviation of image brightness were evaluated from a sequence of images. The short exposure time ensured imaging of the momentary state of the jet while analysis of a sequence of images provided information about jet fluctuations. Effect of arc current was investigated. Arc power increase led to higher fluctuations of the jet, although it caused increase of the jet length.
