Terahertz time-domain spectroscopy of local cow’s tissues

Abstract

This study demonstrates terahertz time-domain spectroscopy characterization of animal tissues obtained from local cow at mart. Terahertz radiation is highly sensitive to the polar molecules of water, thus biological tissues with high level of hydration show strong absorption at terahertz frequencies. All tissue samples are desiccated at same temperature and time scale. The different frequency-dependent response to the terahertz radiation due to the water content are observed from the experimental data of the fat, muscle and mixed of both tissues.
