摘要
化学战剂的实时遥测、可靠识别和定量分析是防化、反恐和国家安全的急需.遥测技术可分为主动和被动两种,主动方式包括差分吸收雷达、开路式拉曼光谱技术、主动傅立叶变换光谱技术、激光诱导荧光技术;被动方式采用太阳、月亮等自然光源,包括时间扫描FTIR光谱技术、空间扫描(静态)FTIR光谱技术和超/多光谱成像技术.将静态高分辨率傅立叶变换红外光谱技术与激光测距技术有机结合,并采用现代模式识别、信号处理技术是化学战剂光谱遥测技术的发展趋势.
Real-time remote detection, reliable discrimination and quantitative analysis for chemical agents are imperative for chemical defense,antiterror and nation security. The remote detection technologies can be classfied as active and passive detection. The active detection includes differential absoption Lidar, open-path Raman spectrum technology, active Fourier transform spectroscopy, laser induced fluorescence, etc. The passive remote detection adopts natural light sources, and consists of time-scan and spatial modulation Fourier transform Infrared （FTIR） spectroscopic technologies, hyperspectral and multispectral imaging technologies. The combination of static high-resolution FTIR, Laser ranging technology, modern pattern recognition and signal processing technology is the developing trend of remote detection for chemical agents.
