Abstract
The paper describes the results of measurements of spectral radiation of the disintegration products of indicator layers by optoelectronic m ethods. The indicator layers, coating the surface of conical models an d prepared on the basis of alkali-metal salts, disintegrate under cond itions of supersonic now of ionized air about the models. The measurem ent scheme is given and theoretical analysis performed of the measurem ent results. Based on the method of ''growth curves'' for radiation in tensity, a method is proposed for determining the temperature and conc entration of alkali-metal vapors in the wail layer of plasma.
