Abstract

The invention relates to an X-ray pinhole camera used under strong laser conditions. The pinhole camera includes a pinhole plate, a pinhole seat shell, a front light tube, a grazing incidence mirror room, a rear light tube, a negative film room, film box, filter frame, filter disc, negative film, two-dimensional adjustment laser seat, semiconductor laser and two-dimensional adjustment frame, the two-dimensional adjustment laser seat is fixedly arranged outside the film chamber, A semiconductor laser is installed on the corresponding side of the chamber, and there are through holes for the adjustment laser to pass through at the optical axis positions of the two-dimensional adjustment laser seat and the film chamber; the invention effectively eliminates the influence of super-strong g-rays under strong laser conditions, making The X-ray pinhole camera is perfectly applied to high-temperature dense plasma imaging under strong laser conditions. The present invention can quickly and stably install and adjust the X-ray pinhole camera of the present invention through the laser-assisted aiming method.

Description

technical field [0001] The invention relates to the field of imaging, in particular to an X-ray pinhole camera and an installation and adjustment method used under strong laser conditions, and is a high-temperature plasma X-ray imaging camera that can be used under conditions of strong laser irradiation and high background noise. Grazing incidence X-ray pinhole camera. Background technique [0002] X-ray pinhole camera is one of the important diagnostic equipment in high-temperature plasma imaging diagnosis, and is widely used in various researches related to high-temperature dense laser plasma. The X-ray pinhole camera can obtain information such as the shape of the laser focal spot, temperature distribution, size, and contour by self-illuminating imaging of the plasma to be measured, which is of great significance for qualitatively understanding the state of the laser focus and the state of the plasma. [0003] The traditional X-ray pinhole camera is based on the principl...
