Transient state phenomenon two-dimensional sequence image multipurpose recording system

Abstract

The invention discloses a multipurpose recording system for two-dimensional sequence images of transient phenomena, which is characterized in that it comprises a target image information generation unit, an image imaging unit, and a control unit for controlling the operation of the target image information generation unit and the image imaging unit; The system is equipped with a rotating mirror ultra-high-speed recording device. Under the control of the control unit, it can not only record the transient phenomenon with large randomness at the moment of detonation, but also perform synchronous photography on the transient phenomenon with little zero drift. ; It can not only be used for waiting for recording when the transient time is shorter than the recording time, but also can be used for waiting for recording when the transient time is longer than the recording time. Under the condition that other conditions remain unchanged, the size of the frame is large and the amount of information in the time direction is high; the small-volume ultra-high-speed electric drive rotating mirror system is easy to use and easy to automatically control; the shutter system is complete and the electronic control system is reliable. It can realize virtual control and real-time visual monitoring; the precision of speed measurement and trigger delay is high.

Description

technical field [0001] The invention relates to image recording technology, in particular to a multi-purpose recording system for two-dimensional sequence images capable of ultra-high-speed recording of transient phenomena.

AI Technical Summary

Problems solved by technology

[0004] Transformer tube technology can achieve ultra-high speed and light enhancement, but the image quality is poor, the frame is small and the number of frames is small (≤8 frames); the grid technology is high in photography frequency, but the number of frames is small and the image quality is poor, so it needs to be "reproduced" Inconvenient to use, very few users; drum technology is difficult to achieve high frequency, and its application is limited; special ultra-high-speed CCD technology is not yet mature, and laser electro-optic shutter technology is limited to specific research fields
