The Applications of Raman Spectroscopy Techniques in Handwriting Verifications

随着市场经济的不断发展和人们法律意识的不断提高，涉及经济合同的案件越来越多，其中包括油墨的鉴定、笔迹的添加和涂改、公章印文的真伪、喷墨和激光打印字迹的鉴定、笔画先后顺序及朱墨时序的鉴定等。由于刑侦鉴定检材有限，且有重要的证据价值，以往采用的鉴定技术和方法，有的对文件物证造成一定损坏，寻找一种快速、准确、无损的检验方法显得尤为重要。而拉曼光谱技术不仅可以实现对检材的零破坏，并且能够快速、有效检出字迹的异同点，从而鉴定不同的笔迹，在司法文书鉴定中取得了令人满意的结果，鉴定结果可以为法庭诉讼提供科学依据。
