Summary: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.
