冷大气压等离子体已经证明了它们支持慢性伤口愈合过程的能力。特别是简单的配置，如介质阻挡放电（DBD），包括一个涂覆有介电层的驱动电极，是令人感兴趣的，因为它们具有成本效益并且易于处理。在治疗过程中，这种等离子体的均匀性是必要的，因为整个伤口应该被均匀地治疗。在这项调查中，相位分辨光学发射光谱被用来调查DBD的均匀性。电子密度和约化电场分布的时间和空间分辨率的确定和施加的正，负电压脉冲的差异进行了研究。
Cold atmospheric pressure plasmas have already proven their ability of supporting the healing process of chronic wounds. Especially simple configurations like a dielectric barrier discharge (DBD), comprising of one driven electrode which is coated with a dielectric layer, are of interest, because they are cost-effective and easy to handle. The homogeneity of such plasmas during treatment is necessary since the whole wound should be treated evenly. In this investigation phase resolved optical emission spectroscopy is used to investigate the homogeneity of a DBD. Electron densities and reduced electric field distributions are determined with temporal and spatial resolution and the differences for applied positive and negative voltage pulses are studied.
