摘要

摘要: 提出了一种基于对比标定的微喷射X光图像面密度数据测量方法，该方法通过中值滤波来减小白斑噪声的影响，利用空场图像来校正光场分布及探测器响应的不均匀性问题，通过对Roll-Bar客体的成像获取系统点扩展函数，并利用成像系统点扩展函数及基于改进的Tikhonov正则化的图像复原方法来减小模糊对X光图像的影响。给出了获取微喷射X光图像面密度信息的处理流程，对静态客体实验图像面密度反演的验证表明，提出的面密度测量方法可以较准确的获取金属微喷射实验X光图像面密度信息。

Abstract: The ejection phenomenon generated by metal materials under strong impact is an important issue in the field of impact compression research. Pulse X-ray photography is an important diagnostic testing method for micro jet processes. The use of X-ray images to obtain the surface density of metal material experimental objects and jets under strong impact is an important objective of this type of experiment. A method for measuring the areal density data of ejection X-ray images based on stepped wedges is proposed. The method reduces the influence of white spot noise by median filtering, corrects the unevenness of light field distribution and detector response by using empty field images, obtains the system point spread function by imaging the Roll-Bar object, and uses the imaging system point spread function and an improved Tikhonov regularization based image restoration method to reduce the impact of blur on X-ray images. The processing flow for obtaining the areal density information of ejection X-ray images is provided. The verification of the inversion of areal density in static object experimental images shows that the proposed areal density measurement method can accurately obtain the areal density information of metal ejection experimental X-ray images.
