Multi-frame framing imaging method, device and equipment

Abstract

The invention relates to a multi-frame framing imaging method, device and equipment. The multi-frame framing imaging method irradiates the corresponding target light to the photocathode through a single hole to generate a corresponding photoelectron image, and uses a sampling separator to sample the photoelectron image. Obtain the sampled electron beams corresponding to different positions in the photoelectron image, focus each sampled electron beam through the electron optical system to obtain their corresponding focused electron beams, and deflect and separate each focused electron beam through the electron beam splitter Processing, generating respective channel electron beams, and scanning each channel electron beam through a scanning electric field, so that each corresponding target electron beam obtained after scanning reaches the fluorescent screen and generates a corresponding fringe image, according to each fringe image The corresponding image at the same time is constructed to obtain the corresponding original target image, which can realize multi-frame framing imaging of a single viewing angle.

Description

technical field [0001] The invention relates to the field of image imaging, in particular to a method, device and equipment for multi-frame framing imaging. Background technique [0002] The framing camera based on photoelectric technology is an indispensable framing imaging device in the field of X-ray ultrafast diagnosis. It has two-dimensional spatial resolution and picosecond time resolution. It has important applications in the study of ultrafast phenomena such as nuclear fusion. [0003] X-rays are not suitable for refraction and have strong penetrability, and the method of framing X-rays cannot be used for framing imaging. Therefore, at present, pinhole arrays (or KB microscopes) and X-ray traveling wave gating framing imaging techniques are mainly used. However, This technology is a non-single viewing angle X-ray framing technology. This is because the pinholes in the pinhole array are distributed according to a certain interval, so that each pinhole corresponds to ...

[0003] X-rays are not suitable for refraction and have strong penetrability, and the method of framing X-rays cannot be used for framing imaging. Therefore, at present, pinhole arrays (or KB microscopes) and X-ray traveling wave gating framing imaging techniques are mainly used. However, This technology is a non-single viewing angle X-ray framing technology. This is because the pinholes in the pinhole array are distributed according to a certain interval, so that each pinhole corresponds to a different azimuth of the measured target, so the distance between each frame There is a difference in viewing angle, causing the light emitted by the same point in the observation target to appear in different positions on different frames, so this technology cannot achieve single viewing angle framing imaging of the target
