Theoretical foundation of a proposed new method of the optical diagnostics of positive column plasma in glow discharge

An integral equation has been constructed which describes the image of cylindrically symmetric, longitudinally homogeneous transparent systems radiating in the optical region. As a base, the construction of the three-dimensional impulse response of a point light source was used. If an experiment is arranged so that it can be described by such an equation, radial variations of atomic concentration in different levels may be determined (e.g., in the positive column of the glow discharge).
