A spectrometric system with a vidicon detector suitable for Abel inversion of spectral line profiles was composed, and a simple procedure for measurement of the lateral distribution of line profiles and for data correction was also proposed.<BR>The background nature of the vidicon was examined, and the influences of the uncertainty of the position of symmetry center and the radius on the Abel inversion was discussed.<BR>Using this system and procedure, the radial and axial distribution of 1-b line in an argonhydrogen plasma jet was determined. The distribution of the electron density was firstly deduced from half-maximum width of Hβ line, and secondly from fitting to the theoretical Stark-broadening line shape. The temperature distribution was determined from the electron density with an assumption of LTE.
