| 摘 要： | 本文分别采用传统拉曼光谱装置及空间偏移拉曼光谱装置，对不/半透明塑料瓶装的NaNO3粉末进行了测量和对比，并对空间偏移拉曼光谱技术对非透明塑料瓶装介质进行有效探测的作用机理进行了分析。空间偏移拉曼光谱技术突破了传统拉曼光谱测量技术的瓶颈（探测深度小，不能对非透明介质覆盖下的深层成分进行探测），实现了对非透明介质（不/半透明塑料瓶）中物质成分(NaNO3)的测量和识别。

| Abstract: | The measurement and contrast of NaNO3 powder concealed in opaque/semi-transparent plastic bottles were carried out through conventional Raman spectroscopy configuration and spatially offset Raman spectroscopy configuration individually. The action mechanism why the spatially offset Raman spectroscopy can effectively detect the medium concealed in the non-transparent bottle was analyzed. The detection depth of conventional Raman spectroscopy is small and the ingredient of the subsurface under non-transparent medium can not be detected, and the spatially offset Raman spectroscopy broke through the neck of the conventional Raman spectroscopy detection. The measurement and identification of the substance concealed in the non-transparent medium (opaque/semi transparent plastic bottle) were realized. |
