Abstract
The monochromatic image of a free-burning arc is acquired with a high-speed camera and narrowband filters. The reconstruction of radial emission coefficients by means of an Abel inversion enables the derivation of the arc temperature. Temperatures obtained from the image are consistent with other measurements. With this technique, the time and spatially resolved properties of arc plasmas can be observed.
