Abstract

The spectral characteristics of corn oil after five minutes and ten minutes of boiling in the rang from 0.2THz to 1.5THz have been measured with THz time-domain spectroscopy (THz-TDS) at room temperature in nitrogen atmosphere. A novel iterative algorithm is employed to determinate the optical properties considering the effect of the cuvette. The refractive indices of the two corn oil samples show slow a decrease as the terahertz wave frequency increases. The power absorption coefficients increase as the frequency increases within the investigated terahertz wave frequency range. The results provided in this paper will help us to study the THz application to seed oil quality and safety detection further.
