Abstract

The non-intrusive optical emission spectroscopy is used to measure the vibrational temperature and the electron density in white-eye pattern in dielectric barrier discharge (DBD) in air. The electron density is investigated by stark broadening of spectral line profile, and the molecule vibrational temperature is calculated by analyzing the intensity ratio of lines in the second positive system (SPS) of N₂ (C³ ∏_u −B³∏_g). The results show that the vibrational temperature and electron density of the spot in white-eye pattern is slightly different from that of the background in white-eye pattern. It indicates that both the spot discharge and the background discharge are microdischarges.
