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.
