摘要/Abstract

摘要：

在L波段三维ESR成像系统的研制中，以Matlab 为平台，建立了包括谱数据自动化处理、ESR空间（1D、2D、3D）成像和ESR谱-空间成像为一体的系统应用软件, 可方便清晰地显示谱和物体自旋密度分布的各种图像，为深入研究顺磁性物种自旋密度分布的特征及其化学反应过程中氧的扩散过程，提供了很好的可视化信息. 实验表明，该系统软件具有广泛的应用前景.

Abstract:

In the development of a L band three dimensional ESR imaging system, a software package of application programs was written with MATLAB (version 6.1), which handles auto-processing of spectral data, and reconstruction of ESR spati al (1D, 2D, 3D) imaging and spectral-spatial imaging. The software can displa y different types of images reconstructed from the spectral data and distribution of spin density in the paramagnetic samples. In addition, this software is cap able of generating useful visible information, which can be applied in the chara
cterization of the spin density distribution of paramagnetic species, as well as in the oxygen diffusion process in chemical reactions.

Key words: ESR, imaging, ESR-CT, filtered back projection, spin density, software
