摘要
为更加系统了解拉曼光谱技术对危化品进行快速检测研究的应用现状,综述国内外对于拉曼光谱检测技术的研究情况,分析5种典型技术(表面增强拉曼光谱技术、共振拉曼光谱技术、共焦显微拉曼光谱技术、傅立叶变换拉曼光谱技术、拉曼光谱与光导纤维联用技术)的优缺点及其在危化品检测方面的应用.研究结果表明:拉曼光谱技术作为1种快速、无损、高灵敏度和高分辨率的检测技术在危化品检测中具有较为广泛的应用前景.目前常用的5种典型拉曼光谱技术均在一定程度上提高了检测灵敏度和分辨率,但均存在不同的局限性.未来的研究应优化和改进拉曼光谱仪功能和结构,研究基于深度学习的拉曼谱图数据库识别模型算法,推进仪器的小型化和特种化,进一步扩展对危化品的检测能力和适用范围.研究结果可为未来基于拉曼光谱的危化品快速检测技术的进一步研究与发展提供参考.
Abstract
To comprehensively comprehend the present state of rapid detection research concerning hazardous chemicals em-ploying Raman spectrum technology,a review of both domestic and international research endeavors in Raman spectrum detec-tion technology was conducted,and the advantages and disadvantages of five representative Raman spectrum detection technol-ogies(surface enhanced Raman spectroscopy,resonance Raman spectroscopy,confocal microscopy Raman spectroscopy,Fou-rier transform Raman spectroscopy,Raman spectroscopy and optical fibers)and their application in chemicals detection were analyzed.The results show that the Raman spectrum technology,characterized by its rapid,non-destructive,highly sensitive,and high-resolution detection capabilities,holds considerable promise for application in the identification of hazardous chemi-cals.The future research endeavors should focus on optimizing and enhancing the functionality and structure of Raman spec-trometers,studying the recognition model algorithm of Raman spectrum graph database based on deep learning,and advancing efforts in miniaturization and specialization of spectral instruments,so as to further expand the detection capability of hazard-ous chemicals and application scope.The research results can provide reference for the further research and development of rapid detection technology of hazardous chemicals based on Raman spectrum in the future.
