Rotating mirror type microsecond level process time-space information improvement recorder

Abstract

The invention discloses a rotating mirror type microsecond level process time-space information improvement recorder which comprises an imaging system and a support system. The imaging system comprises an objective lens, a shutter combination, a beam split waiting device, two secondary light split devices, framing devices corresponding to the secondary light split devices respectively, a scanning device and a framing scanning rotating mirror device. Due to the fact that a framing light path and a scanning light path share the same objective lens, the light paths have the same space benchmark. Due to the fact that the framing light path and the scanning light path share the same double-entrance oblique incidence waiting type trihedron rotating mirror, and the two light paths conduct reflection imaging through the same rotating mirror, and thus have the same time benchmark. Two-dimension image information is obtained through the framing devices, and image information within a one-dimension slit with successive time is obtained through the scanning device. Through the framing, scanning and simultaneous imaging of the same time benchmark and the same space benchmark, improvement information of a microsecond level process can be obtained, and high judgment accuracy and precision are obtained.

Description

technical field [0001] The invention relates to a rotating mirror microsecond-level process time-space information perfect recorder. Background technique [0002] High-speed imaging technology is a time-magnifying technology for observing transient events, which can give time-space 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 and migration of phonons and excitons in solids; the study of molecular structure dynamics, photosynthesis important in the...

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

Later, 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
