Kirlian Photography as a Type of Plasma Photography

Abstract

The authors consider Kirlian photography to be a type of plasma photography, where the generation of the latent image in the photosensitive layer is caused by the light emitted by the plasma (primary radiation) and by incident charged particles from the plasma (secondary radiation). The dependence of the structure and colour of Kirlian photographs on the shape of the electric excitation pulses, measured spectra of the primary radiation and evaluation of the penetration of ions in the tilms used, support this concept.
