实时监测激光核聚变靶球涂敷状态的CCD成像系统设计

介绍一种CCD 成像系统的设计，它可应用于连续监测直径0.1-0.3mm 的激光核聚变靶球涂
敷时的实时状态。这个系统利用现成照相物镜和变焦显微物镜二次成像，配以场镜压缩轴外光线，和CCD 传感器相组合，设计斜向视场上的二维扫描机构构成了可8.2mm×44mm 全视场扫描检测的CCD 扫描成像系统，无论是空间分辨力或时间分辨力都达到了实时监测的要求，大大提高了靶球膜层的涂敷效率。

Abstract: The design of a CCD imaging system is introduced. It can be applied to continuously monitoring the real-time status of micro-sphere in laser fusion target with a diameter of 0.1-0.3mm. By using secondary imaging carried out by the ready objective and the zoom micro-objective, combined with field lens for compressing off-axis rays and CCD sensor, a CCD scanning and imaging system which can scan and detect the field of 8.2mm´44mm is constructed with a 2-D scanning mechanism. No matter its spatial resolution or time resolution has attained the requirements for real-time monitor, and the coating efficiency for micro-sphere film is greatly improved.
