摘　　要：光谱编码指的是将有限的光谱信号输出进行组合,从而得到更多光谱信号输出的手段,满足了高通量的生物检测和成像及高容量信息存储等需求。通常用于光谱编码的信号输出包括荧光光谱、拉曼光谱和反射光谱等。其中,拉曼光谱由于带宽窄、不易重叠,尤其是生物静默区的三键拉曼谱带尖锐、特异,无背景干扰,在光谱编码领域潜力巨大。本文综述了拉曼光谱编码技术的类型和编码方法,同时还介绍了拉曼光谱编码在生物医学检测、成像及信息安全等领域的应用。Spectral coding refers to the means of combining the limited spectral signal output to obtain more spectral signal output,which meets the requirements of high-throughput biological detection and imaging and high-capacity information storage.The output of signal usually used for spectral coding includes fluorescence spectrum,Raman spectrum and reflection spectrum.Among them,the Raman spectra have great potential in the field of spectral coding due to the narrow band width and difficult overlap,especially the three-bond Raman spectra in the bio-silent zone with sharp,specific band and no background interference.In this paper,the types and coding methods of Raman spectral coding are reviewed,and the applications of Raman spectral coding in biomedical detection,imaging and information security are also introduced.
