摘要：
The terahertz time-domain spectroscopy (THz-TDS) is used to measure absorption spectra in crushed wheat grain over the frequency range of 0.1-2.0 THz. A number of well resolved absorption peaks are ohserved for dry, 12%, 14% and 18% moisture content levels. Subtracting, the transmission signal spectra of the dry flour from that of the wetted flour provides a calibrated result which relates attenuation to moisture content level.
