The technique of spatially resolved cross-correlation spectroscopy is used to carry out diagnostic measurements of the barrier discharge in air at atmospheric pressure. Quantitative estimates for electric field strength E(x,t) and for relative electron density ne(x,t)/nemax are derived from the experimentally determined spatio-temporal distributions of the luminosity for the spectral bands of the 0-0 transitions of the 2nd positive system of N2 (? = 337.2 nm) and the 1st negative system of N2+ (? = 391.5 nm). Experimental results related to the investigations of coronas and pulsed spark discharges are briefly reviewed.
