Using a holographic imaging, high speed spectroscopy of the electric explosion of a cop-per wire in air has been recorded at rates between 3×105 to 4×105 frames per second. As a result of the experiment, a few line spectra of neutral copper atoms were observed after restrike occured, which were not observed during the first electric current pulse.
The success of the present work seems to indicate the usefulness of using the hologra-phic imaging for the spectrum analysis of rapid self-luminous phenomenon.
