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5ns,像面空间分辨率优于37lp/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。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,biolumines- cence,laser induced fluorescence, and possess a broad application prospect.
