technical field [0001] The invention belongs to the technical field of image detection, and in particular relates to an image detection device for framing, delaying and detecting light images based on an image framing and time-delay structure and an image intensification camera, specifically a framing image detection device and method, It is suitable for acquiring multiple high-time-resolved light image information of different time series in a single time. Background technique [0002] Obtaining multiple high-time-resolution optical image information at different time sequences plays an important role in the research fields of physics, chemistry, and biomedicine, and is an important means of analyzing and studying ultrafast processes. The traditional framing camera performs multi-framing processing on the optical image through a beam splitting optical path based on a beam splitter or a mirror, etc., and then records it by multiple image-intensifying cameras. Each image-enha...

Problems solved by technology

However, this method also has the following disadvantages. The opening time of each door is controlled by high-voltage electric pulses, and the time relationship between each framing image is related to the fluctuation of the relative delay of high-voltage electric pulses.

The optical path structure of the system is complex, and the integrated volume is large. The complex optical path structure also results in low light collection efficiency and limits the sensitivity of the system.

In addition, each image-enhanced camera can only obtain one framed image, and more cameras are needed to obtain more framed images. The increase in the number of frames will increase the cost and increase the difficulty of system integration
