The present invention provides a control device and method based on two rotating mirror ultra-high-speed cameras working synchronously. The control device for synchronous operation of the rotating mirror ultra-high-speed camera can meet the needs of high-speed process testing in weapon research. The invention includes a processor, a two-way camera rotating mirror circuit, a two-way electromagnetic shutter circuit and other auxiliary circuits. The invention is applicable to the application field of rotating-mirror ultra-high-speed photography technology.

Description

technical field [0001] The invention relates to the technical field of high-speed photography, in particular to a control device and method based on the synchronous operation of two mirror-rotating ultra-high-speed cameras. Background technique [0002] High-speed photography is one of the important optical testing methods in the research fields of detonation physics, shock wave physics, accelerator physics and plasma experiments. Because the shooting frequency of the rotating mirror ultra-high-speed camera ranges from tens of thousands of frames per second to 10 7 frame / second, the spatial resolution is 20-30 lp / mm, and these performances it has are irreplaceable by current digital cameras or video tube cameras. The rotating mirror is an important part of the optical system in the ultra-high-speed camera. The optical device, the rotating mirror is in a high-speed rotation state when the ultra-high-speed camera works. However, the rotating mirror ultra-high-speed camera, wh...
