摘要
印章的鉴定是法庭科学的重要组成部分,为了更好的打击刑事犯罪,文章提出了采用傅里叶变换红外图像系统对骑缝章的形成进行了快速无损鉴别研究。结合面扫描和反射模式,先对骑缝章不同部位进行可见图像和红外图像扫描,然后根据印油的红外谱图中吸收峰位置或其特征吸收峰的吸光度比值来鉴定骑缝章是否为一次性形成。红外谱图的结果表明,如果是一次性形成的骑缝章,印油红外谱图中吸收峰位置或其特征吸收峰的吸光度比值基本相近;如果非一次性形成的骑缝章,印油红外谱图中吸收峰位置或其特征吸收峰的吸光度比值相差很大。该法具有快速、准确、客观和不损坏样品等特点。
Seal＇s determination is the important part of forensic science. In order to better beat criminality, the authors brought forward a new method to study the making process of connective seal fast and nondestuctively by means of FTIR imagine Sys- tem. Combining the surface scan and reflectance mode, the different part of connective seal was seaned firstly, then according to the characteristic absorption proportion of stamp-pad ink it was determined whether the connective seal was one-off made or not. The results showed that if the connective seal was one-off made, the characteristic absorption proportion was equal. This method is rapid, accurate, impersonal and nondestructive.
