Nanosecond pulsed discharges have been applied to industrial processes such as exhaust-gas treatment. To improve pulse-generation efficiency, various diagnostics have been conducted, and measurements of optical emission intensity are particularly important for understanding discharge properties and mechanisms. An event camera asynchronously records pixel-wise changes in brightness with high temporal resolution and a wide dynamic range. In this study, we report observations of the optical emission from a nanosecond pulsed discharge using an event camera, capturing its spatiotemporal evolution.
