Research on the Recovery Technology of Damaged Characters Based on the Magneto-optical Method

Abstract

This work intends to address the issue of surface damage to significant characters on ferromagnetic materials for the assessment of physical evidence. For the identification of altered metallic characteristics, a nondestructive magneto-optical imaging recovery approach based on the magneto-optical effect is presented. The results of the experiments demonstrate that the technique may successfully repair the damaged metallic features. It can be used as a nondestructive test for the examination and restoration of altered and damaged metal handwriting in criminal technology, which offers a fresh approach and method to deal with this issue.
