Hyperspectral imaging (HSI) has become a crucial innovation in forensic science, particularly for analysing bodily fluids. This advanced technology captures both spectral and spatial data across a wide spectrum of wavelengths, offering comprehensive insights into the composition and distribution of bodily fluids found at crime scenes. In this review, we delve into the forensic applications of HSI, emphasizing its role in detecting, identifying, and distinguishing various bodily fluids such as blood, saliva, urine, vaginal fluid, semen, and menstrual blood. We examine the benefits of HSI compared to traditional methods, noting its non-destructive approach, high sensitivity, and capability to differentiate fluids even in complex mixtures. Additionally, we discuss recent advancements in HSI technology and their potential to enhance forensic investigations. This review highlights the importance of HSI as a valuable tool in forensic science, opening new pathways for improving the accuracy and efficiency of crime scene analyses.
高光谱成像（HSI）已成为法医学领域的一项关键创新，尤其适用于分析体液。这项先进技术在广泛的波长范围内捕获光谱和空间数据，提供有关犯罪现场发现的体液组成和分布的全面见解。在本综述中，我们深入探讨了 HSI 在法医中的应用，强调其在检测、识别和区分各种体液（如血液、唾液、尿液、阴道液、精液和月经血）方面的作用。我们比较了 HSI 与传统方法的优势，指出其非破坏性方法、高灵敏度以及区分即使在复杂混合物中也能区分体液的能力。此外，我们还讨论了 HSI 技术的最新进展及其在增强法医调查方面的潜力。本综述强调了 HSI 作为法医学中一种有价值工具的重要性，为提高犯罪现场分析的准确性和效率开辟了新途径。
