快速中药光谱成像检测分析系统设计

Detection and analysis for spectral imaging TCM assessing

为了实现中药的快速、无损、实时检测和分析,设计了一个中药光谱成像检测分析系统,实现了在计算机上通过控制界面对光谱成像硬件系统中的滤光器和摄像机等关键器件的同步、联动控制,以获取一定波长间隔的系列光谱图像,经过软件的分析处理,得到中药样品的二维特征光谱曲线和空间三维成分分布曲线,实现了中药成分的定性和空间分布的实时检测。

Spectral imaging traditional Chinese medicine（TCM） assessing method can be used to evaluate the quality of the medicine.In order to realize the fast,non-destructive and real-time detection and analysis of TCM,software is designed to control the components and take the spectral images.In the system,there are two key components,VariSpec Liquid Crystal Tunable Filter and CCD camera,which can be controlled by the software.The CCD camera obtains a series of spectral images with a specific wavelength interval by controlling the two components simultaneously and automatically.In addition,the software can draw two-dimensional characteristic spectrum curve and spatial distribution curve of three-dimensional of the TCM after processing the original spectral images.The results show that the software is available to control the components to detect the content of the TCM and draw its spatial distribution.
