This paper presents an optical emission spectroscopy (OES) method for measuring the distribution of energetic electrons in multi-needle-to-plate corona discharge. The intensity of N-2 second positive band peak I-SPB in the discharge gap was detected, and the morphology of the ionization region was determined. The results showed that the sum of I-SPB in the ionization region was approximately linear in the discharge current I and the total number of energetic electrons n. Meanwhile, according to the relationship between the velocity of energetic electron v and the value of E/p in the corona discharge, n was determined at different applied voltages U. Finally, according to the spatial distribution of I-SPB in the ionization region, the relative density distribution of the energetic electrons was determined.
