摘　　要：根据X射线多针孔成像的原理,搭建了地面模拟成像装置进行X射线成像实验,获得了像素能量沉积(灰度值)与X射线强度、像素位置与入射角之间的关系,验证了采用多针孔成像技术探测近地太空核爆的可行性,为今后采用编码孔成像技术探测近地太空核爆提供基础。The ground experimental device has been set up for X- ray imaging experiment based on the princi- ple of X - ray multi - pinhole imaging. The relationships between the image gray value and the intensity of X - ray, the image pixel position and the incident angle of X - ray are obtained, so the feasibility of measuring the near - earth space nuclear detonation using X - ray multi - pinhole imaging technology is verified. This result can provide reference for the measurement of the near - earth space nuclear detonation using X - ray coded ap- erture imaging technology.
