X-RAY STREAK CAMERA IMAGING PERFORMANCE TESTING SYSTEM AND METHOD

摘要

The present invention relates to an X-ray streak camera imaging performance testing system and method. The present invention is manufactured based on electronic optical MTF theory and a reticle type photoelectric cathode, the spatial resolution of a streak camera is measured, and the SMTF, DMTF and extreme spatial resolution of the streak camera are calculated under two working modes of a static testing mode and a dynamic testing mode on a large-working area X-ray streak camera. By means of the method, the extreme spatial resolution distribution of all imaging regions of a streak camera can be obtained by fitting experimental measurement data, so as to provide important significance for realizing laser ICF quantitative and semi-quantitative measurement and "refinement" of a diagnosis target.
