拉曼光谱在液体安检中的应用及发展趋势

Application and Development of Raman Spectroscopy in Liquid Security Inspection

在民航、轨道交通、重要场馆安保等领域的液体安检中,现在主要的技术有三种:介电常数测量技术、拉曼光谱分析技术以及基于X射线的检测技术,但每种技术都不能单独地满足实际需求。拉曼光谱技术可以在液体安检以及违禁品检测中发挥重要作用。未来拉曼光谱技术将在以下方面得到发展:1、采用新技术提升仪器性能;2、增加谱图库扩大技术的应用范围;3、与表面增强拉曼光谱技术结合实现违禁品的探测。

There are three main technologies used in the liquid security inspection in civil aviation,mass transit,and important places security：dielectric permittivity measurement techniques,X-ray-based detection technology,and Raman spectroscopy.Existing technologies alone can not meet the needs of actual demand.Raman spectroscopy technology could play an important role in liquid security inspection and contraband inspection.Raman spectroscopy will be developed in the following areas：1,performance improving of the instrument by using new techniques;2,expanding application area by increasing the spectrum;3,realizing contraband detection by using surface-enhanced Raman spectroscopy.
