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。

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.
