Paper Abstract

The principles of the polychromatic holographic interferometry (PHI) with line spectra have been developed. This method allows us to investigate simultaneously spatial and spectral characteristics of various objects. The general theory of the formation of interference fringes in the PHI, which takes into account the dependence of the object refractive index on wavelength and the experimental conditions, has been constructed and the quantitative criteria for the necessity of this general theory application have been determined. Optical schemes and light source equipment for the PHI have been developed and the possibility of the PHI with the use of a `comb-like' laser generation and gas-discharge light sources is shown. The PHI have been applied for plasma diagnostics and new diagnostic possibilities appearing due to the PHI application have been demonstrated.
