Abstract

A micro-scanning space-time resolution measuring system comprises a high-voltage power supply, a gate pulse generator and a micro-scanning image converter tube. The micro-scanning image converter tube comprises a disc-shaped flange, a coaxial connector, a PCB substrate, a fluorescent screen, a gain-free microchannel board, a cathode microstrip line, an external intensifier and a visible light CCD. The micro-scanning space-time resolution measuring system is adopted, the transition time of emergent photoelectrons is short, the spatial resolution superior to 5 microns is achieved, and meanwhile the time resolution of the system can be greatly improved.

Description

technical field [0001] The invention relates to a gate control framing technology in ultra-high-speed imaging technology, in particular to a micro-scanning space-time resolution measurement system. Background technique [0002] Ultra-high-speed imaging is an important tool for human beings to explore the unknown world. To some extent, the level of imaging technology can determine the level of physical understanding. The multi-dimensional photography method with high time resolution and high spatial resolution under the same system can provide key experimental observation methods for exploring ultrafast physical processes, plasma physical evolution, celestial body evolution, and biodynamics research. In the current ultra-high-speed imaging technology, there are mainly two technical approaches: one is fringe scanning technology, which can achieve one-dimensional time resolution and one-dimensional spatial resolution; the other is gated framing technology, which is currently ...
