DBD Plasma Discharges in Air at Atmospheric Pressure: Photographs and Electrical Waveforms

Description This dataset contains paired photographs and oscilloscope measurements of DBD plasmas generated in air at atmospheric pressure. The measurements span a wide parameter grid of excitation frequencies, transformer drive levels (“voltage [%]”), camera exposure times, and discharge gap widths. Electrical and optical measurements were acquired quasi-automatically over ~3 weeks, with randomized sequencing to reduce time-dependent biases. Optical data were post-processed into a quantitative table with statistics, texture, and ISO 25178 surface parameters, and each operating point was manually labeled by discharge coverage.
