Abstract

Recent applications of the scanning electron microscope (SEM) have been in areas such as paint samples evaluation [1,2] and firing pin impressions [3,4], These have provided useful additional information to the forensic scientist. This investigation was conducted to further expand the applicability of the SEM and the developed imaging techniques for use on other forms of physical evidence. Specifically, striations on copper-jacketed bullets and contaminant particles recovered from personal articles (clothing, shoes, etc) were chosen.
