Abstract
The possibility of obtaining local contours of spectral lines of strongly inhomogeneous doubly ionized nitrogen plasma with the help of a system that involves a spectrograph and a megapixel CCD matrix is shown. An automated measuring system based on a CCD matrix is described, and a procedure for processing matrix spectra is presented. The results of the Abel transform of the chord distributions of spectral line intensities of ions with different degrees of ionization are presented. Determined local contours of spectral lines can be used for estimating local temperatures and electron concentrations in strongly ionized spatially inhomogeneous plasmas.
