Paper Abstract
Using the terahertz time-domain spectroscopy (THz-TDS), the frequency-dependent absorption coefficient(s) and
refractive index (indices) of selected lube base oil (LBO) were extracted in the spectral range of 0.3-1.6 THz. The
selected LBO was also characterized by near-infrared spectrum. The experimental results reveal that LBO is more
sensitive in the THz range than near-infrared, and the different viscosity index of LBO can be identified according to
their different spectral features in THz range. Due to better repeatability, shorter testing time, and easy operation, THz-
TDS can be used as a complementary for identifying the chemical composition of LBO.
