摘　　要：在研究介质阻挡放电照相机理和质量的基础上 ,采用高压纳秒脉冲介质阻挡放电技术 ,以硬币、植物叶片以及人体手指为样品 ,对五种应用实例进行了实验尝试和讨论 .结果表明 ,用该方法在拍摄单一色彩的非平面图案时 ,所得的图像比用普通光学摄影获得的图像更完整、清晰 ,且对比度高 .该技术可应用于非平面样品图案图像的提取和复印、植物新鲜程度的鉴别、人体指纹的获取以及特殊摄影等领域 .Five kinds of applications of dielectric barrier discharge photography (DBDP) are studied experimentally and discussed by using the high voltage nanosecond pulse dielectric barrier discharge technology with the specimens such as coin, plant leaf and human's finger. The results show that for photographing the monochromatic non-plane pattern, the images obtained by this technology are more perfect, clearer and has higher contrast than those obtained by common photography. This technology can be applied in these areas in the future such as the non-plane pattern obtaining and duplicating, acquirement of fingerprints, distinguishment of the freshness of plant, and other special photography.
