摘要
光谱成像技术是一种集合光谱技术和成像技术的方法,能获取被检物体的空间信息和光谱信息,形成三维的光谱影像集.作为一种快速、无损的光学检验方法,光谱成像技术能满足法庭科学对物证检验的要求,尤其在痕迹物证的显现、识别、分类方面具有十分重要的作用.对光谱成像技术的基本原理和流程进行介绍,概述了其在法庭科学文件检验、血迹检验、指纹检验等领域的前沿应用,并分析了法庭科学领域光谱成像技术发展存在的困境和未来趋势,以促进该技术进一步发展,使其更好地服务于法庭科学工作.
Abstract
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.
