    • Abstract
  • Super-resolution restoration is employed with image converted tube streak camera to improve time resolution of camera. The feasibility of the image of streak camera being processed by super-resolution restoring is presented. The point spread function of streak image is described and formulated. The image restoration results of X-ray streak camera of Au photocathode are obtained with Poisson-MMAP（MPMAP）algorithm. The experimental results show that the super-resolution image restoration on ultra-fast diagnosis can be used for improving time resolution of image converted tube streak camera.
