Abstract

Having previously generated frequency-tunable terahertz (THz) waves from GaP, we constructed a THz spectral measurement system with an automatic scanning control. We demonstrate the use of this THz spectrometer for measuring the transmittance spectra of D-(+)-glucose, 2-deoxy-D-glucose, D-(-)-fructose, and D-(+)-sucrose in the 0.8 to 5.5 THz (25 to 185 cm-1) frequency region with a spectral resolution of 3.2 GHz (0.1 cm-1), using a pyroelectric detector operated at room temperature. Each crystalline saccharide had different spectral features.
