研制了一种阴极有效直径为15mm、荧光屏输出面直径为40mm的可见光条纹管。利用光学纤维面板作为阴极输入光窗,实现了光学上零厚度的目标,提高了光能传输效率和图像传输质量。依据阴极和荧光屏显示面积设计了一种放大率适中的电子光学系统,实现了较大探测狭缝的目标。测试结果显示,条纹管的静态空间分辨率达到25lp/mm以上,时间分辨率优于20ps,满足高速信号探测中较大狭缝尺寸条纹管的应用需求。
Developed a cathode effective diameter of 15mm, fluorescent screen output surface diameter of 40mm visible light striped tube. The optical fiber panel is used as a cathode input light window, achieving the goal of optical zero thickness and improving the light energy transmission efficiency and the image transmission quality. According to the display area of cathode and phosphor screen, a kind of electronic optical system with moderate magnification was designed, which realized the goal of large detection slit. The test results show that the static spatial resolution of the stripe pipe reaches more than 25lp / mm and the time resolution is better than 20ps, which meets the application requirements of larger slit size stripe tubes in high-speed signal detection.
