使用基于液晶可调谐滤光器的光谱成像检测系统,对西洋参及市面上常用做假冒西洋参的伪品桔梗进行了在体检测.该系统能对检品进行连续光谱成像,光谱分辨率可达0.5 nm,配合使用Matlab软件对图像信号进行处理和分析.获取了400 nm～680 nm之间的连续荧光光谱图像,通过对比西洋参、桔梗的特征光谱曲线,及进行相关系数的计算,有效地区分了西洋参及桔梗.为西洋参的真伪鉴别提供了一定的帮助.

This paper introduced a spectral imaging detection system which is based on a liquid crystal tunable filter. The system can get the samples'spectral image continuously. Its spectral resolution is up to 0.5 nm. We processed and analyzed the image with Matlab software. The system was used to carry out in vivo test of Panacis quinquefolii and its pseudo products Platycodi. We obtained the fluorescence spectra image between 400 nm～680 nm. By comparing their characteristic spectral curve and calculating the correlation coefficient, we could differentiate the American ginseng and its counterfeit effectively. It provides a method for identifying the authenticity of Panacis quinquefolii.
