Optical waiting type plane imaging system for framing, scanning and simultaneous recording

Abstract

The invention relates to an optical waiting type plane imaging system for framing, scanning and simultaneous recording, comprising an objective lens, a waiting light splitter, two secondary light splitters, a framing device and a scanning device which are arranged corresponding to each secondary light splitter and a framing and scanning rotating mirror device. Two times of light splitting are realized by the waiting light splitter and the secondary light splitters, a framing optical path and a scanning optical path which are generated after light splitting both enter the framing and scanning rotating mirror device, and images are generated on a framing image plane and a scanning image plane respectively; as the framing optical path and the scanning optical path are provided with a commonobjective lens, the two paths have the same space datum and generate reflection images by the same rotating mirror, and the two paths have the same time datum, thus obtaining higher space informationand time information, high interpretation accuracy and high interpretation precision.

Description

【Technical field】 [0001] The invention relates to a framing and scanning imaging system, and more specifically relates to a plane imaging system applied to optical waiting type framing scanning and simultaneous recording in high-speed imaging technology. 【Background technique】 [0002] High-speed imaging technology is a time-magnifying technology for observing transient events, which can give space-time information of high-speed changing processes. High-speed imaging technology has experienced the development process from high-speed to very high-speed, ultra-high-speed, and extremely high-speed, from visible light to far-infrared, ultraviolet, and X-rays, from the study of the motion of macroscopic objects to the study of microscopic mechanisms. [0003] High-speed imaging technology is used in the study of emission and collision-like transient processes; the study of detonation-like ultrafast processes and high-voltage discharge-like transient processes; the study of decay ...

AI Technical Summary

Problems solved by technology

Therefore, although the entire recorder uses only one camera, which is an improvement compared to the early framing and scanning simultaneous recorder, it is still difficult to achieve due to the existence of two sets of rotating mirror systems with different system time references. Precise time synchronization and consistent speed

Afterwards, the United States studied recorders with a common space reference and a common time reference, but these recorders used a spatial beam optical system with low spatial resolution and a complex system structure (Manfred Held.
