压电变压器 (PT) 可用作低压条件下的放电激励器。在PT表面极化电荷产生的电场中引起放电，并在PT周围观察到发光。观察光发射和电势的空间分布。这些结果清楚地表明，PT 表面上的电势分布与发光强度的空间分布相当一致。还使用电荷耦合器件相机系统捕获光发射的时间变化，以研究光发射的动态行为。
Piezoelectric transformers (PTs) can be utilized as discharge exciters in low-pressure conditions. The discharge is caused in the electric field produced by the polarization charge on the surface of the PT, and the light emission is observed around the PT. Spatial distributions of the light emission and the potential are observed. These results clearly show that potential distribution on the PT surface agrees fairly with spatial distribution of luminous intensity. Temporal variations of light emission are also captured using a charge coupled device camera system to investigate the dynamic behavior of light emission.
