洛斯·阿拉莫斯国家实验室研究出一种用于探测大气中微量有毒分子的激光技术。在同步探测激光感应荧光的基础上,该技术使大有机分子的复杂混合物可以分解成组成它的成分。据研究人员Gerard Quigley宣称,在遥感探测环境中的致癌物及有毒化学物质方面,该技术将是有用的。因为大有机分子的荧光是宽带,且无相应特色,所以不同分子的光谱往往会重叠,以致几乎不可辨认。采用喇曼散射处理,可部分地克服这个问题,基于独特的振动模式,喇曼散射允许识别单个分子,然而,喇曼信号往往太弱,以致于对遥感应用是无用的。
Los Alamos National Laboratory has developed a laser technology for the detection of trace toxic molecules in the atmosphere. Based on the simultaneous detection of laser-induced fluorescence, this technique allows complex mixtures of large organic molecules to be broken down into the components that make up it. According to researcher Gerard Quigley, the technology will be useful in the field of detecting carcinogens and toxic chemicals in the environment. Because the fluorescence of large organic molecules is broadband and has no corresponding characteristics, the spectra of different molecules tend to overlap and are almost indistinguishable. Raman scattering processing partially overcomes this problem. Based on the unique vibrational mode, Raman scattering allows the recognition of individual molecules. However, Raman signals are often too weak to be useful for remote sensing applications.
