A system is presented for registering shadow images obtained from dense pulsed plasma with a high background illumination level, wherein an LGI-21 molecular nitrogen laser is used as an illuminator (laser pulse power 12 µW, duration 20 ns), and a modified Canon EOS 1000D camera is used as a registering unit. A micropinch discharge such as a high-current low-inductance vacuum spark (HCLIVS) has been used as the plasma object under investigation.

在强烈背景照明条件下在紫外光谱范围内记录快速过程阴影图像的系统

提出了一种用于记录从具有高背景照明水平的密集脉冲等离子体中获得的阴影图像的系统，其中使用LGI-21分子氮激光器作为照明器（激光脉冲功率为12 µW，持续时间为20 ns），并使用改良的佳能EOS 1000D相机用作注册单元。诸如大电流低电感真空火花（HCLIVS）之类的微缩放电已被用作研究中的等离子体对象。
