Visualization of a Restored Serial Number Using Scanning Electron Microscopy (SEM)
The restoration of obliterated serial numbers by both chemical and physical means has been well documented in the field of forensic science. An interesting case of a severely obliterated serial number was submitted to our laboratory for restoration. Despite development with Fry's etchant, the visualization, documentation, and photography of the restored serial number proved difficult because of the deep “pock” type of obliteration. The scanning electron microscope was explored as a potential means for assisting in the examination of the restored serial number. The scanning electron microscope successfully provided a simple means for the visualization, documentation, and photography of the restored serial number.
