Abstract Dielectric barrier discharges (DBD) under atmospheric pressure in helium or in air were carried out at a higher frequency. Lissajous figures of single pulse glow, multi-pulse glow and filamentary discharges were investigated, applied voltage and current pulses were measured, and discharge photos were taken by ICCD in an exposure time of ns order. The results show that for both glow discharges, the discharge mode at the discharge inception for each current pulse is a Townsend one, and that at the discharge current peak is a glow one. Lissajous figure of glow discharges by a applied voltage with a high frequency is a quadrilateral with one step on the left-hand, right-hand sides respectively, and a set of parallel lines of the top and the bottom sides. In the case of multi-pulse discharges, the number of steps on the left hand side or the right hand one of Lissajous figures is equal to the number of current pulses per half-cycle of the applied voltage. The Lissajous figure of a filamentary DBD is approximately a parallelogram, and a much less complicated interpretation is proposed.
