It is shown that the optical emission method, based on measured spatial and spectral distributions of the Halpha radiation, provides valuable information on physical conditions in the volume of dielectric-barrier discharges. In the case when the registration allows the determination of light polarization, the measured spectra may provide information about the distribution of the electric-field strength in a direction that is perpendicular to the surfaces limiting the discharge volume. Visualization of the experimental data of spatial distributions of the hydrogen Halpha line is presented.
