Application of Spectral Imaging Technology in Field of Forensic Science
Spectral imaging is a method that integrates spectral and imaging techniques to extract spatial information and spectral information of an object to form a three-dimensional hypercube.As a fast and nondestructive optical inspection method,spectral imaging can meet the requirements of forensic science for examining physical evidence.Specifically,it plays a crucial role in the appearance,identification,and classification of trace evidence.In this study,the principle and workflow of spectral imaging are introduced,followed by cutting-edge applications in forensic science,such as examinations of document,blood stain,and fingerprint.Furthermore,the dilemma and future trend of spectral imaging are analyzed to promote further technological development that can serve forensic science.
