Abstract:The terahertz (THz) waves are the electromagnetic waves in the range from 0.1 to 10 THz. THz waves has very unique
natures, rich scientific contents as well as broad application prospects. As many skeleton vibrations of macro-molecules fall in the THz
band, it is suitable for the use of THz waves to detect those information. THz time-domain spectrometer (TDS) is capable of obtaining
information of the THz pulses. In this paper, based on THz TDS, we gave an example of authenticity identification of Angelicae
dahuricae Radix and Ligusticum chuanxiong hort to show our recent work, which providing a method for pattern recognition of other
medicines and foods.
