As a kind of molecular spectroscopy technology,Raman spectroscopy plays an important role in forensic document examination with the merits of quick testing and non-destructive to samples.With the development of science and technology,new techniques of Raman spectroscopy and artificial intelligence tools make it more widely used.After a brief introduction of the principle and classification of Raman spectroscopy,this paper mainly reviews the application and research progress of Raman spectroscopy in the field of forensic document examination at home and abroad in recent years,including the discrimination of inks,analysis of document formation time,identification of altered documents and inspection of special kind of documents.The authors suggested to combine Raman spectroscopy with other analytical techniques,extend testing scopes,and improve the construction of Raman spectroscopy database,to promote the development of document inspection towards a more standardized,scientific,and efficient direction.
