Description

technical field [0001] The invention relates to a high-frame-rate and high-sensitivity imaging system, in particular to a high-frame-rate camera system with the function of remote real-time acquisition of high-frame-rate images. Background technique [0002] The high frame rate imaging system can well reflect the details of the motion process of the research object, so as to obtain some valuable information. It is widely used in scientific experimental research fields such as crash tests, plasma physics, explosion phenomena, and battlefield reconnaissance. In some applications, not only the high frame rate of the camera is required, but also remote image monitoring is required, such as plasma physics research and explosion phenomenon research. The former is very harmful to researchers because the research object has high radiation rays; the latter Or, due to the destructive shock waves and explosion fragments at the explosion site, which may cause physical injury to research...
