A method for analyzing the structure of light responses in the glow patterns of a field projector has been developed. An algorithm for identifying areas corresponding to individual emission sites has been proposed. A theory of the occurrence of the halo effect, associated with the elastic rebound of electrons from the surface of the phosphor, has been confirmed. Keywords: field emission, field emission projector, halo effect.
