Fast ICCD was utilized to register images and spectrally-resolved emission of individual micro-discharges synchronously either with high voltage waveforms or with micro-discharge current pulses. Build-up and decay time constants of several excited states together with streamer channel diameter were obtained for an isolated micro-discharge which is essentially free of an interference that might be caused by reactive species produced and left by preceding discharges. Such characteristics provide important benchmarks for more complex surface DBD geometries where accumulation of species capable of affecting the physical chemistry of micro-discharges readily occurs.
