共焦显微拉曼光谱深度剖析法在笔迹鉴定中的应用

利用共焦显微拉曼光谱纵向扫描采样手段，发展了一种深度剖析光谱方法在法庭科学领域的新应用，并将此方法具体运用到了书写笔迹与印章印泥的鉴定，在纵向上区分笔迹和印泥的空间位置上取得了很好效果。该方法具有快速、简便、灵敏度高、对样品无损伤等优点。

Application of Depth-Analysis of Confocal Raman Micro-Spectroscopy to Chirography Identification

Depth analysis of confocal Raman micro-spectroscopy was applied to chirography identification. The result indicated that depth analysis has potential application to forensic science field, especially in longitudinal identification of ink and inkpad. No matter what the spatial distributions of the signature pen and inkpad are, confocal Raman micro-spectroscopy can longitudinally distinguish those spatial differences. All those suggested that confocal Raman micro-spectroscopy is a fast, simple, high sensitive and non-destructive technique.
