Abstract

The invention relates to the technical field of high-speed photography, and in particular relates to a control device and method based on synchronous working of two rotating mirror type ultrahigh-speed cameras. The control device and method aim at solving the problems in the prior art, and acquiring the state characteristics of different positions and different development stages of the same high-speed process. According to the control device based on the synchronous operation of the two rotating mirror type ultrahigh-speed cameras, requirements of high-speed process tests in weapon research can be met. The control device comprises a processor, two paths of camera rotating mirror circuits, two paths of electromagnetic shutter circuits and other auxiliary circuits. The control device and the control method are applied to the field of technical application of rotating mirror type ultrahigh-speed photography.

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 two rotating-mirror ultra-high-speed cameras working synchronously. Background technique [0002] High-speed photography is one of the important optical testing methods in research fields such as detonation physics, shock wave physics, accelerator physics and plasma experiments. Since the shooting frequency of the rotating mirror ultra-high-speed camera ranges from tens of thousands of frames per second to 10 7 frames per second, and the spatial resolution is 20-30 lp / mm. Its performances cannot be replaced by current digital cameras or tube cameras. Rotating mirrors are important in the optical system of ultra-high-speed cameras. The optical device, the rotating mirror is in a high-speed rotating state when the ultra-high-speed camera is working. However, when the rotating mirror ultra-high-speed camera is used alone, it canno...
