Accurate Determination of Geographical Origin of Tea Based on Terahertz Spectroscopy

This paper proposes a structured model for the identification of green tea, as well as tracing its geographical origins. Considering that the features of different types of green tea are similar under THz time-domain spectroscopy, we designed a program to perform principal component analysis (PCA) o...
