【摘要】 发光体内部空间发光强度的分布规律是无法通过探测设备直接测量的.本文以轴对称汞光源为例,提出了运用CT层析技术原理,通过测量发光体的弦积分光强,利用Abel逆变换进行反演,测量发光体内部发光强度径向相对分布规律的实验方法.实验系统设计简单,计算方法容易实现,既可作为研究性实验应用于实验教学,也可作为一种测量手段用于科学研究领域.更多还原

【Abstract】 The distributions of interior radial intensity of a Hg light source are measured. The experimental methods are based on the well-known CT technology, and the data are processed by the inversion transformations. The experiment system is easy to assemble and the computations are implemented. This method can be used not only in the teaching activities, but also in the research fields as well.更多还原
