Abstract

The invention relates to an ultrahigh-speed framing camera system and an ultrahigh-speed framing camera imaging method. The ultrahigh-speed framing camera system comprises an electric control system, a pinhole plate, a framing pipe assembly and an image acquisition module for acquiring and recording, and carrying out data analysis, wherein the pinhole plate, the framing pipe assembly and the image acquisition module are sequentially arranged on a path for sending out an optical signal of a target source. The invention provides the ultrahigh-speed framing camera system which can be used for improving the time resolution of a framing camera to 40ps without improvement on performances of a micro-channel plate and high-voltage gating pulse, is simple to manufacture and is convenient to use, and also provides the ultrahigh-speed framing camera imaging method.

Description

technical field [0001] The invention belongs to the field of high-speed photoelectric imaging, and relates to a vacuum photoelectric imaging device and an image processing method, in particular to an ultra-high-speed framing camera system and an imaging method. Background technique [0002] X-ray framing camera is an important tool for the research of laser nuclear fusion and laser plasma physics. Since the entire action process of laser plasma only occurs within a few nanoseconds, ultrafast framing imaging technology emerges at the historic moment. The X-ray framing camera is used to observe the two-dimensional shape of the plasma temperature and density changing with time during the inertial confinement fusion (ICF) experiment. It is used in the study of hydrodynamic instability, implosion dynamics and compression symmetry and X-ray backlight photography research has a wide range of applications. [0003] In the study of ICF implosion dynamics and interface diagnosis, th...
