Temperatures in air plasma jet were measured using a tomographic experimental arrangement providing time-resolved scans of plasma optical radiation in the spectral band 559-601 nm from 2 directions. The acquired data and subsequent processing yielded time-resolved temperature distributions in measurement planes perpendicular to the plasma jet axis with temporal resolution 1 ms. The measurement system and evaluation methods afforded the detailed information about influence of high-frequency ripple modulation of the arc current on plasma temperature.
