摘要

摘要: 通过深入研究增强型电荷耦合器(ICCD)中的关键单元——耦合器、快脉冲电源和精密延时同步控制单元, 自行研制了一套可见光ICCD系统。测试结果表明:ICCD的最短曝光时间为5 ns, 像面空间分辨率优于37 lp/mm。将该ICCD应用在透射式纹影测试光路上, 进行了高压击穿空气放电考核实验, 获得了清晰的实验图像。实验结果表明, 所研制的可见光ICCD的成像质量较高, 可满足等离子体放电、喷射物分析、生物体发光、激光诱导荧光等瞬态超快过程诊断需求, 应用前景广阔。

Abstract: In this paper, we developed a visible light intensified charge coupled device (ICCD) and introduced its key elements including the coupler, the fast pulse power and the high-precision delay synchronization control unit.The test results show that the ICCD's shortest exposure time is 5 ns, and the image spatial resolution is better than 37 lp/mm.Using this newly developed ICCD, we set up a special transmission schlieren optical system for measuring the process of high-voltage air discharge, and obtained remarkably clear images, thereby enabling the ICCD to present a high-quality level and meet such ultrafast transient diagnostic requirements as plasma discharge, ejecta analysis, bioluminescence, laser induced fluorescence, and possess a broad application prospect.
