利用三维电磁仿真软件CST模拟设计了一款小型电聚焦条纹管,在模拟中采用了正交实验法来确定条纹管各电极间距离及各电极电压。同时,根据条纹管像差定义对其像质进行了全面的理论分析和评价。优化设计的条纹管阴极有效工作面积直径大于28 mm,物理时间分辨率优于30 ps,边缘静态空间分辨率大于20 lp/mm,条纹管放大倍率为1.07,总管长仅为100 mm,管外围直径为50 mm。满足航天、空间探测以及海洋执法等应用领域非扫描式激光雷达技术对大探测面积、超小型条纹变像管的应用需求。
A three-dimensional electromagnetic simulation software CST simulation design of a small electric focusing stripe tube, in the simulation using orthogonal experimental method to determine the distance between the stripe tube electrodes and the electrode voltage. At the same time, a comprehensive theoretical analysis and evaluation of its image quality are carried out according to the definition of the striped tube aberration. Optimized cathode effective working area of the striped tube is larger than 28 mm in diameter, the physical time resolution is better than 30 ps, the static spatial resolution of the edge is more than 20 lp / mm, the magnification of the striped tube is 1.07 and the total tube length is only 100 mm. The diameter is 50 mm. Meet aerospace, space exploration and maritime law enforcement applications such as non-scanning laser radar technology for large detection area, the application of ultra-small streaks change tube.
