摘要： 根据投影切片原理, 设计了一个简单而有效的ESR图象重建算法和程序, 可利用样品的一集ESR谱, 方便地绘制出样品在某截面的自旋密度立体轮廓图、等值图和散点密度分布图等, 为分析和研究自旋密度的分布及其性质, 提供了直观依据。作为应用, 文中给出了石英杜瓦受紫外光辐照后产生的局部晶格缺陷——F心的空间分布图, 图中清楚表明, F心的浓度与辐照方向和辐照强度的密切关系, 与试验结果完全相符。

Abstract: In this article, a simple and efficient algorithm has been designed for reconstructing ESR image, on the basis of projection profile principle, which can be used to plot contour, stereograph and dispersal-point distribution graph of the sample sipn density distribution on a cross-section. As an example, the ESR image of paramagnetic defect centers in quartz Dewar due to UV-irradiation was given to illustratethe appli-cation of the algorithm.
