摘要：

In this paper, we used the partial least square method and terahertz spectroscopy to identify the four kinds of radix curcumae, there are hangyujin, lvyujin, wenyujin, guiyujin respectively. By using the terahertz spectroscopy system, we measured terahertz spectroscopy of the four kinds of radix curcumae. Then, does Fourier transform with these terahertz spectroscopy and get the absorption coefficient as the feature data for the identification. At last, using the partial least squares method, we can identify the four kinds of radix curcumae successfully. (C) 2012 Elsevier GmbH. All rights reserved.
