为满足激光三维成像技术对小型化、大探测面积条纹管的要求,同时解决现有条纹管采用球形荧光屏存在的问题,利用MATLAB软件设计了一种采用平面荧光屏的小型条纹管。经过电子轨迹跟踪和图像质量评价,波纹管阴极的有效工作直径为30 mm,边缘静态极限空间分辨率优于42 lp/mm,放大倍数略大于1,管径为50 mm,长度为126 mm。
Aiming at satisfying the requirement of laser three-dimensional imaging technology for miniaturization and large detection area streak tube, and also to resolve the potential problems of using spherical screen in existing streak tube, a mini streak tube with planar fluorescent screen was designed by using MATLAB software. After electronic trajectory tracking and image quality evaluation, the effective working diameter of the bellows cathode is 30 mm, the static limit spatial resolution of the edge is better than 42 lp/mm, the magnification is slightly greater than 1, the diameter of the tube is 50 mm, and the length is 126 mm.
