【摘要】：化学成像技术结合光谱分析和成像技术从而同时获得物质的光谱和空间各点的组成和结构信息。振动光谱方法(红外和拉曼光谱)与成像相结合,具有灵敏、快速、无损检验等优点,能够为检验鉴定提供定性定量的准确信息,近年来在物证鉴定领域获得了重要的应用。手印的显现和增强有多种方法,化学成像技术作为一种潜力巨大的方法可以显现多种客体上的潜在手印而不需要任何前处理。该技术还可以增强用其他方法显现后的手印,使之与背景形成较大反差。随着成像仪器的发展,化学成像技术在手印显现领域的应用将会一步拓展。文章介绍了化学成像技术的基本原理和仪器,综述了化学成像技术在潜在手印的显现和增强方面的具体应用,展望了化学成像技术的发展前景。
[Abstract]:Chemical imaging technology combines spectral analysis and imaging techniques to simultaneously obtain the composition and structure information of the spectral and spatial points of matter. Vibration spectroscopy (IR and Raman spectroscopy) combined with imaging has the advantages of sensitivity, rapidity and nondestructive testing, which can provide accurate qualitative and quantitative information for testing and identification, and has been applied in the field of physical evidence identification in recent years. There are many ways to show and enhance handprints. As a potential method, chemical imaging technology can show the potential handprints on a variety of objects without any pre-processing. This technique can also enhance the handprint which is displayed by other methods, making it a big contrast with the background. With the development of imaging instruments, the application of chemical imaging technology in the field of hand print display will be expanded step by step. This paper introduces the basic principles and instruments of chemical imaging technology, summarizes the application of chemical imaging technology in the manifestation and enhancement of potential hand prints, and looks forward to the development prospect of chemical imaging technology.
